MAX3232EEPE中文资料

General DescriptionThe MAX3222E/MAX3232E/MAX3237E/MAX3241E are 3V-powered EIA/TIA-232 and V.28/V.24 communications interfaces with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD)protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-G ap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge,and ±15kV using the Human Body Model. In addition, the MAX3237E’s logic and receiver I/O pins are protected to the above ESD standards.The transceivers have a proprietary low-dropout transmit-ter output stage, delivering true RS-232 performance from a +3.0V to +5.5V supply with a dual charge pump. The charge pump requires only four small 0.1µF capacitors for operation from a +3.3V supply. Each device is guaran-teed to run at data rates of 250kbps while maintaining RS-232 output levels. The MAX3237E is guaranteed to run at data rates of 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode while main-taining RS-232-compliant output levels.The MAX3222E/MAX3232E have two receivers and two drivers. The MAX3222E features a 1µA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers can remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1µA supply current.Both the MAX3222E and MAX3232E are pin, package,and functionally compatible with the industry-standard MAX242 and MAX232, respectively.The MAX3241E is a complete serial port (three drivers/five receivers) designed for notebook and sub-notebook computers. The MAX3237E (five drivers/three receivers) is ideal for peripheral applications that require fast data transfer. Both devices feature a shutdown mode in which all receivers can remain active while using a supply current of only 1µA (MAX3241E) or 10nA (MAX3237E). The MAX3237E/MAX3241E have additional receiver outputs that always remain active.The MAX3222E, MAX3232E, and MAX3241E are avail-able in space-saving SO, SSOP, and TSSOP packages.The MAX3237E is available in an SSOP package.________________________ApplicationsBattery-Powered Equipment PrintersCell PhonesSmart Phones Cell-Phone Data Cables xDSL ModemsNotebook, Subnotebook, and Palmtop ComputersFeatureso ESD Protection for RS-232 I/O Pins(MAX3222E/MAX3232E/MAX3237E/MAX3241E)±15kV—Human Body Model±8kV—IEC 1000-4-2, Contact Discharge ±15kV—IEC 1000-4-2, Air-Gap Discharge o ESD Protection For All Logic and Receiver I/O Pins (MAX3237E)±15kV—Human Body Model±8kV—IEC 1000-4-2, Contact Discharge ±15kV—IEC 1000-4-2, Air-Gap Discharge o Guaranteed Data Rate250kbps (MAX3222E/MAX3232E/MAX3241E and MAX3237E, Normal Operation)1Mbps (MAX3237E, MegaBaud Operation)o Latchup Freeo Low-Power Shutdown with Receivers Active1µA (MAX3222E/MAX3241E)10nA (MAX3237E)o Flow-Through Pinout (MAX3237E)o Guaranteed Mouse Driveability (MAX3241E)o Meets EIA/TIA-232 Specifications Down to 3.0VMAX3222E/MAX3232E/MAX3237E/MAX3241E †±15kV ESD-Protected, Down to 10nA, 3.0V to 5.5V ,Up to 1Mbps, True RS-232 Transceivers________________________________________________________________Maxim Integrated Products119-1298; Rev 5; 3/02MegaBaud is a trademark of Maxim Integrated Products, Inc.†Covered by U.S. Patent numbers 4,636,930; 4,679,134; 4,777,577; 4,797,899; 4,809,152; 4,897,774; 4,999,761; and other patents pending.For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 3222E /M A X 3232E /M A X 3237E /M A X 3241E±15kV ESD-Protected, Down to 10nA, 3.0V to 5.5V ,Up to 1Mbps, True RS-232 TransceiversABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The charge pump operates in discontinuous mode; if the output voltages are less than 5.5V, the charge pump is enabled, and if the output voltages exceed 5.5V, the charge pump is disabled. Each charge pump requires a flying capacitor (C1, C2) and a reservoir capacitor (C3, C4) to generate the V+ and V- supplies (Figure 1).RS-232 TransmittersThe transmitters are inverting level translators that con-vert TTL/CMOS-logic levels to ±5.0V EIA/TIA-232 com-pliant levels.The MAX3222E/MAX3232E/MAX3237E/MAX3241E transmitters guarantee a 250kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF, providing compatibility with PC-to-PC communication software (such as LapLink ™). Transmitters can be paralleled to drive multiple receivers or mice.The MAX3222E/MAX3237E/MAX3241E ’s transmitters are disabled and the outputs are forced into a high-imped-ance state when the device is in shutdown mode (SHDN =GND). The MAX3222E/MAX3232E/MAX3237E/MAX3241E permit the outputs to be driven up to ±12V in shutdown.The MAX3222E/MAX3232E/MAX3241E transmitter inputs do not have pullup resistors. Connect unused inputs to G ND or V CC . The MAX3237E ’s transmitter inputs have a 400k Ωactive positive feedback resistor,allowing unused inputs to be left unconnected.MAX3237E MegaBaud OperationFor higher-speed serial communications, the MAX3237E features MegaBaud operation. In MegaBaud operating mode (MBAUD = V CC ), the MAX3237E transmitters guarantee a 1Mbps data rate with worst-case loads of 3k Ωin parallel with 250pF for 3.0V < V CC < 4.5V. For 5V ±10% operation, the MAX3237E transmitters guarantee a 1Mbps data rate into worst-case loads of 3k Ωin parallel with 1000pF.RS-232 ReceiversThe receivers convert RS-232 signals to CMOS-logic output levels. The MAX3222E/MAX3237E/MAX3241E receivers have inverting three-state outputs. Drive EN high to place the receiver(s) into a high-impedancestate. Receivers can be either active or inactive in shut-down (Table 1).The complementary outputs on the MAX3237E/MAX3241E (R_OUTB) are always active, regardless of the state of EN or SHDN . This allows the device to be used for ring indica-tor applications without forward biasing other devices con-nected to the receiver outputs. This is ideal for systems where V CC drops to 0 in shutdown to accommodate peripherals such as UARTs (Figure 2).MAX3222E/MAX3237E/MAX3241EShutdown ModeSupply current falls to less than 1µA in shutdown mode (SHDN = low). The MAX3237E ’s supply current falls to10nA (typ) when all receiver inputs are in the invalid range (-0.3V < R_IN < +0.3). When shut down, the device ’s charge pumps are shut off, V+ is pulled down to V CC , V- is pulled to ground, and the transmitter outputs are disabled (high impedance). The time required to recover from shutdown is typically 100µs,as shown in Figure 3. Connect SHDN to V CC if the shut-down mode is not used. SHDN has no effect on R_OUT or R_OUTB (MAX3237E/MAX3241E).±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated to protect against electrostatic dis-charges encountered during handling and assembly.The driver outputs and receiver inputs of the MAX3222E/MAX3232E/MAX3237E/MAX3241E have extra protection against static electricity. Maxim ’s engi-neers have developed state-of-the-art structures to pro-tect these pins against ESD of ±15kV without damage.The ESD structures withstand high ESD in all states:normal operation, shutdown, and powered down. After an ESD event, Maxim ’s E versions keep working without latchup, whereas competing RS-232 products can latch and must be powered down to remove latchup.Furthermore, the MAX3237E logic I/O pins also have ±15kV ESD protection. Protecting the logic I/O pins to ±15kV makes the MAX3237E ideal for data cable appli-cations.LapLink is a trademark of Traveling Software.8MAX3222E/MAX3232E/MAX3237E/MAX3241E±15kV ESD-Protected, Down to 10nA, 3.0V to 5.5V ,Up to 1Mbps, True RS-232 Transceivers_______________________________________________________________________________________9ESD protection can be tested in various ways; the transmitter outputs and receiver inputs for the MAX3222E/MAX3232E/MAX3237E/MAX3241E are characterized for protection to the following limits:•±15kV using the Human Body Model•±8kV using the Contact Discharge method specified in IEC 1000-4-2•±15kV using IEC 1000-4-2’s Air-G ap Discharge method ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 4a shows the Human Body Model, and Figure 4b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of inter-est, which is then discharged into the test device through a 1.5k Ωresistor.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and per-formance of finished equipment; it does not specifically refer to integrated circuits. The MAX3222E/MAX3232E/MAX3237E/MAX3241E help you design equipment that meets Level 4 (the highest level) of IEC 1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak current in IEC 1000-4-2 because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 1000-4-2 is generally lower than that measured using the Human Body Model. Figure 5a shows the IEC 1000-4-2 model, and Figure 5b shows the current waveform for the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.The Air-G ap Discharge test involves approaching the device with a charged probe.

Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. All pins require this protection during manufacturing, not just RS-232 inputs and outputs.Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.Applications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical for proper operation; polarized or nonpolarized capacitors can be used. The charge pump requires 0.1µF capaci-tors for 3.3V operation. For other supply voltages, see Table 2for required capacitor values. Do not use val-ues smaller than those listed in Table 2. Increasing the capacitor values (e.g., by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without changing C1’s value. However, do not increase C1without also increasing the values of C2, C3, C4,and C BYPASS to maintain the proper ratios (C1 to the other capacitors).Figure 4a. Human Body ESD Test Model Figure 4b.

If in doubt, use capaci-tors with a larger nominal value. The capacitor ’s equiv-alent series resistance (ESR), which usually rises at low temperatures, influences the amount of ripple on V+and V-.Power-Supply DecouplingIn most circumstances, a 0.1µF V CC bypass capacitor is adequate. In applications that are sensitive to power-supply noise, use a capacitor of the same value as charge-pump capacitor C1. Connect bypass capaci-tors as close to the IC as possible.Operation Down to 2.7VTransmitter outputs will meet EIA/TIA-562 levels of ±3.7V with supply voltages as low as 2.7V.Transmitter Outputs when Recovering from ShutdownFigure 3shows two transmitter outputs when recover-ing from shutdown mode. As they become active, the two transmitter outputs are shown going to opposite RS-232 levels (one transmitter input is high, the other is low). Each transmitter is loaded with 3k Ωin parallel with 2500pF. The transmitter outputs display no ringing or undesirable transients as they come out of shutdown.Note that the transmitters are enabled only when the magnitude of V- exceeds approximately -3V.Mouse DriveabilityThe MAX3241E has been specifically designed to power serial mice while operating from low-voltagepower supplies. It has been tested with leading mouse brands from manufacturers such as Microsoft and Logitech. The MAX3241E successfully drove all serial mice tested and met their respective current and volt-age requirements. Figure 6a shows the transmitter out-put voltages under increasing load current at 3.0V.Figure 6b shows a typical mouse connection using the MAX3241E.High Data RatesThe MAX3222E/MAX3232E/MAX3237E/MAX3241E maintain the RS-232 ±5.0V minimum transmitter output voltage even at high data rates. Figure 7shows a trans-mitter loopback test circuit. Figure 8shows a loopback test result at 120kbps, and Figure 9shows the same test at 250kbps. For Figure 8, all transmitters were driven simultaneously at 120kbps into RS-232 loads in parallel with 1000pF. For Figure 9, a single transmitter was driv-en at 250kbps, and all transmitters were loaded with an RS-232 receiver in parallel with 1000pF.The MAX3237 maintains the RS-232 ±5.0V minimum transmitter output voltage at data rates up to 1Mbps.Figure 10shows a loopback test result at 1Mbps with MBAUD = V CC . For Figure 10, all transmitters were loaded with an RS-232 receiver in parallel with 250pF.Interconnection with 3V and 5V LogicThe MAX3222E/MAX3232E/MAX3237E/MAX3241E can directly interface with various 5V logic families, includ-ing ACT and HCT CMOS.

L=15µH+8Ω+15µH Array 200558249Application InformationGENERAL AMPLIFIER FUNCTIONThe output signals generated by the LM4666consist of two,BTL connected,output signals that pulse momentarily from near ground potential to V DD on each channel.The two outputs on a given channel can pulse independently with the exception that they both may never pulse simultaneously as this would result in zero volts across the BTL connected load.The minimum width of each pulse is approximately 160ns.However,pulses on the same output can occur se-quentially,in which case they are concatenated and appear as a single wider pulse to achieve an effective 100%duty cycle.This results in maximum audio output power for a given supply voltage and load impedance.The LM4666can achieve much higher efficiencies than class AB amplifiers while maintaining acceptable THD performance.The short (160ns)drive pulses emitted at the LM4666out-puts means that good efficiency can be obtained with mini-mal load inductance.The typical transducer load on an audio amplifier is quite reactive (inductive).For this reason,the load can act as it’s own filter,so to speak.This "filter-less"switching amplifier/transducer load combination is much more attractive economically due to savings in board space and external component cost by eliminating the need for a filter.POWER DISSIPATION AND EFFICIENCYIn general terms,efficiency is considered to be the ratio of useful work output divided by the total energy required to produce it with the difference being the power dissipated,typically,in the IC.The key here is “useful”work.For audio systems,the energy delivered in the audible bands is con-sidered useful including the distortion products of the input signal.Sub-sonic (DC)and super-sonic components (>22kHz)are not useful.The difference between the power flowing from the power supply and the audio band power being transduced is dissipated in the LM4666and in the transducer load.The amount of power dissipation in the LM4666is very low.This is because the ON resistance of the switches used to form the output waveforms is typically less than 0.25Ω.This leaves only the transducer load as a po-tential "sink"for the small excess of input power over audio band output power.The LM4666dissipates only a fraction of the excess power requiring no additional PCB area or cop-per plane to act as a heat sink.DIFFERENTIAL AMPLIFIER EXPLANATIONAs logic supply voltages continue to shrink,designers are increasingly turning to differential analog signal handling to preserve signal to noise ratios with restricted voltage swing.The LM4666is a fully differential amplifier that features differential input and output stages.A differential amplifier amplifies the difference between the two input signals.Tra-ditional audio power amplifiers have typically offered only single-ended inputs resulting in a 6dB reduction in signal to noise ratio relative to differential inputs.The LM4666also offers the possibility of DC input coupling which eliminates the two external AC coupling,DC blocking capacitors.The LM4666can be used,however,as a single ended input amplifier while still retaining it’s fully differential benefits.In fact,completely unrelated signals may be placed on the input pins.The LM4666simply amplifies the difference be-tween the signals.A major benefit of a differential amplifier isthe improved common mode rejection ratio (CMRR)over single input amplifiers.The common-mode rejection charac-teristic of the differential amplifier reduces sensitivity to ground offset related noise injection,especially important in high noise applications.PCB LAYOUT CONSIDERATIONSAs output power increases,interconnect resistance (PCB traces and wires)between the amplifier,load and power supply create a voltage drop.The voltage loss on the traces between the LM4666and the load results is lower output power and decreased efficiency.Higher trace resistance between the supply and the LM4666has the same effect as a poorly regulated supply,increase ripple on the supply line also reducing the peak output power.The effects of residual trace resistance increases as output current increases due to higher output power,decreased load impedance or both.To maintain the highest output voltage swing and corre-sponding peak output power,the PCB traces that connect the output pins to the load and the supply pins to the power supply should be as wide as possible to minimize trace resistance.The rising and falling edges are necessarily short in relation to the minimum pulse width (160ns),having approximately 2ns rise and fall times,typical,depending on parasitic output capacitance.The inductive nature of the transducer load can also result in overshoot on one or both edges,clamped by the parasitic diodes to GND and V DD in each case.From an EMI standpoint,this is an aggressive waveform that can radiate or conduct to other components in the system and cause interference.It is essential to keep the power and output traces short and well shielded if e of ground planes,beads,and micro-strip layout techniques are all useful in preventing unwanted interference.As the distance from the LM4666and the speakers increase the amount of EMI radiation will increase since the output wires or traces acting as antenna become more efficient with length.What is acceptable EMI is highly application specific.Ferrite chip inductors placed close to the LM4666may be needed to reduce EMI radiation.The value of the ferrite chip is very application specific.POWER SUPPLY BYPASSINGAs with any power amplifier,proper supply bypassing is critical for low noise performance and high power supply rejection ratio (PSRR).The capacitor (C S )location should be as close as possible to the LM4666.Typical applications employ a voltage regulator with a 10µF and a 0.1µF bypass capacitors that increase supply stability.These capacitors do not eliminate the need for bypassing on the supply pin of the LM4666.A 1µF tantalum capacitor is recommended.SHUTDOWN FUNCTIONIn order to reduce power consumption while not in use,the LM4666contains shutdown circuitry that reduces current draw to less than 0.01µA.The trigger point for shutdown is shown as a typical value in the Electrical Characteristics Tables and in the Shutdown Hysteresis Voltage graphs found in the Typical Performance Characteristics section.It is best to switch between ground and supply for minimum current usage while in the shutdown state.While the LM4666may be disabled with shutdown voltages in between ground and supply,the idle current will be greater than theL M 466610Application Information(Continued) typical value.Increased THD may also be observed with voltages less than V DD on the Shutdown pin when in PLAY mode.The LM4666has an internal resistor connected between GND and Shutdown pins.The purpose of this resistor is to eliminate any unwanted state changes when the Shutdown pin is floating.The LM4666will enter the shutdown state when the Shutdown pin is left floating or if not floating,when the shutdown voltage has crossed the threshold.To mini-mize the supply current while in the shutdown state,the Shutdown pin should be driven to GND or left floating.If the Shutdown pin is not driven to GND,the amount of additional resistor current due to the internal shutdown resistor can be found by Equation(1)below.(V SD-GND)/60kΩ(1)With only a0.5V difference,an additional8.3µA of currentwill be drawn while in the shutdown state.GAIN SELECTION FUNCTIONThe LM4666has fixed selectable gain to minimize externalcomponents,increase flexibility and simplify design.For adifferential gain of6dB,the Gain Select pin should be per-manently connected to V DD or driven to a logic high level.For a differential gain of12dB,the Gain Select pin should bepermanently connected to GND or driven to a logic low level.The gain of the LM4666can be switched while the amplifieris in PLAY mode driving a load with a signal without damageto the IC.The voltage on the Gain Select pin should beswitched quickly between GND(logic low)and V DD(logichigh)to eliminate any possible audible artifacts from appear-ing at the output.For typical threshold voltages for the GainSelect function,refer to the Gain Threshold Voltages graphin the Typical Performance Characteristics section.LM466611Application Information(Continued)CIRCUIT CONFIGURATIONS20055803FIGURE 2.Single-Ended input with low gain selection configuration20055802FIGURE 3.Differential input with low gain selection configurationL M 4666 12Application Information(Continued) REFERENCE DESIGN BOARD SCHEMATICIn addition to the minimal parts required for the application circuit,a measurement filter is provided on the evaluation circuit board so that conventional audio measurements can be conveniently made without additional equipment.This is a balanced input,grounded differential output low pass filter with a3dB frequency of approximately35kHz and an on board termination resistor of300Ω(see schematic).Note that the capacitive load elements are returned to ground. This is not optimal for common mode rejection purposes,but due to the independent pulse format at each output there is a significant amount of high frequency common mode com-ponent on the outputs.The grounded capacitive filter ele-ments attenuate this component at the board to reduce the high frequency CMRR requirement placed on the analysis instruments.Even with the grounded filter the audio signal is still differ-ential necessitating a differential input on any analysis instru-ment connected to it.Most lab instruments that feature BNC connectors on their inputs are NOT differential responding because the ring of the BNC is usually grounded.The commonly used Audio Precision analyzer is differential but its ability to accurately reject fast pulses of160ns width is questionable necessitating the on board measurement filter. When the signal needs to be single-ended,use an audio signal transformer to convert the differential output to a single ended output.Depending on the audio transformer’s characteristics,there may be some attenuation of the audio signal which needs to be taken into account for correct measurement of performance.Measurements made at the output of the measurement filter suffer attenuation relative to the primary,unfiltered outputs even at audio frequencies.This is due to the resistance of the inductors interacting with the termination resistor(300Ω) and is typically about-0.35dB(4%).In other words,the voltage levels and corresponding power levels indicated through the measurement filter are slightly lower than those that actually occur at the load placed on the unfiltered out-puts.This small loss in the filter for measurement gives a lower output power reading than what is really occurring on the unfiltered outputs and its load.The AUX-0025Switching Amplifier Measurement Filter from Audio Precision may be used instead of the on board mea-surement filter.The AUX-0025filter should be connected to the high current direct outputs on the evaluation board and in series with the measurement equipment.Attaching oscillo-scope probes on the outputs of the AUX-0025filter will display the audio waveforms.The AUX-0025filter may also be connected to the on board filter without any adverse effects.20055801FIGURE4.LM4666 13Application Information(Continued)LM4666SDA BOARD ARTWORKComposite ViewSilk Screen2005580520055808Top Layer Internal Layer 1,GND2005580920055806Internal Layer 2,V DDBottom Layer2005580720055804L M 4666 14Physical Dimensionsinches (millimeters)unless otherwise notedLLP PackageOrder NumberLM4666SD NS Package Number SDA14ALIFE SUPPORT POLICYNATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION.As used herein:1.Life support devices or systems are devices or systems which,(a)are intended for surgical implant into the body,or (b)support or sustain life,and whose failure to perform when properly used in accordance with instructions for use provided in the labeling,can be reasonably expected to result in a significant injury to the user. 2.A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system,or to affect its safety or effectiveness.BANNED SUBSTANCE COMPLIANCENational Semiconductor certifies that the products and packing materials meet the provisions of the Customer Products Stewardship Specification (CSP-9-111C2)and the Banned Substances and Materials of Interest Specification (CSP-9-111S2)and contain no ‘‘Banned Substances’’as defined in CSP-9-111S2.National Semiconductor Americas Customer Support CenterEmail:new.feedback@ Tel:1-800-272-9959National SemiconductorEurope Customer Support CenterFax:+49(0)180-5308586Email:europe.support@Deutsch Tel:+49(0)6995086208English Tel:+44(0)8702402171Français Tel:+33(0)141918790National Semiconductor Asia Pacific Customer Support CenterEmail:ap.support@National SemiconductorJapan Customer Support Center Fax:81-3-5639-7507Email:jpn.feedback@ Tel:81-3-5639-7560LM4666Filterless High Efficiency Stereo 1.2W Switching Audio AmplifierNational does not assume any responsibility for use of any circuitry described,no circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry and specifications.。

July 2000ML4664*/ML4669*10BASE-FL to 10BASE-T ConverterGENERAL DESCRIPTIONThe fully pin-compatible ML4664/ML4669 pair provide conversion from 10BASE-T copper media to 10BASE-FL fiber media in a single chip. They are compliant with Ethernet IEEE 802.3 10BASE-T and 10BASE-FL standards.The ML4664/69 uses a single 5V supply, and requires no crystal or clock.Their 10BASE-FL transmitter offers a current drive output that directly drives a fiber optic LED transmitter. Their receiver offers a highly stable fiber optic data quantizer capable of accepting input signals as low as 2mV P-P with a 55dB dynamic range.The 10BASE-T portion of the pair contains current driven transmitter outputs that offer superior performancebecause their switching is highly symmetric, resulting in lowered RFI noise and jitter. By changing one external resistor the pair easily interfaces to 100W unshielded twisted pair, 150W shielded twisted pair, or a range of other characteristic impedances.The ML4664 does not pass along disconnect information,while the ML4669 does. A loss of light at the optical inputs does not stop link pulses from being sent at the twisted pair transmitter in the ML4664, but in the ML4669 the link pulses stop. Also, a loss of link at the twisted pair inputs will not stop the optical transmitter from sending idle in the ML4664, but the ML4669 stopssending idle. * Some Packages Are ObsoleteFEATURESs Full duplex operations Five network status LED outputs sIndustrial temperature option10BASE-FL FEATURES:sHighly stable data quantizer with 55dB input dynamic ranges Input sensitivity as low as 2mV P-PsUp to 100mA maximum current driven fiber optic LED output for accurate launch power (PLCC package)10BASE-T FEATURES:s Current driven output for low RFI noise and low jitter sDrives 100W unshielded or 150W shielded twisted pairs Polarity detect status pin capable of driving an LED s Automatic polarity correction s On-chip link test with enable/disable option BLOCK DIAGRAMOPINOPOUT OPVCC元器件交易网元器件交易网ML4664/ML4669PINNAMEFUNCTION1(29)C TIMERA capacitor from this pin to V CCdetermines the Link Monitor response time.2(30)LTFLink Test Fail.

If the link goes down resulting from the absence of link pulses or frames being received, the chip will go into the Link Test Fail state and bring LTF high.When the ML4664 is in the link test fail state, the optical and twisted pair transmitters are disabled from sending data. However, the optical transmitter does send an idle signal, and link pulses are sent at the twisted pair transmitter. When the ML4669 is in link test fail state, the optical and twisted pair transmitters are disabled from sending data. Also, the optical transmitter will not send an idle signal. However, link pulses may be sent at the twisted pair transmitter,depending on the optical inputs. See Table 1.This pin may be grounded to disable Link Test.

See equation (1) on page 9. The increased current option is not available for the CH (TQFP) package option.元器件交易网元器件交易网ML4664/ML4669 SYSTEM DESCRIPTIONOPTICAL TRANSMISSIONThe optical transmit function consists of detecting thepresence of data from the TP inputs TPINP and TPINN anddriving that data onto the fiber optic LED transmitter. Apositive signal on the TPINP lead relative to the TPINNlead will result in no current, hence the fiber optic LED isin a low light condition. When TPINP is more negativethan TPINN, the ML4664/ML4669 will sink current intothe chip and the fiber optic LED will light up.Before data will be transmitted onto the fiber optic cableit must exceed the squelch requirements. The TP inputs,squelch circuit serves the function of preventing any noisefrom being transmitted onto the fiber.FIBER OPTIC LED DRIVERThe output stage of the transmitter is a current modeswitch which develops the output light by sinking currentthrough the LED into the OPOUT pin. Once the currentrequirement for the LED is determined, the RTSETOPresistor is selected. The following equation is used toselect the correct RTSETOP resistor:RTSETOP=52mAI OUT´115W(1)The ML4664/ML4669 optical transmitter (in the PLCC package only) is capable of driving up to 100mA maximum which requires resistor RSTETOP to equal 60W. (This option is only available with the PLCC package) The transmitter enters the idle state when it detects start of idle on TPINP and TPINN input pins. After detecting the start of idle the transmitter switches to a 1MHz output idle signal.The output current is switched through the OPOUT pin during the on cycle and the OPVCC pin during the off cycle. Since the sum of the current in these two pins is constant, OPVCC should be connected as close as possible to the V CC connection for the LED.TP SQUELCHThe twisted pair receive data is transformer coupled and low pass filtered before it is fed into the input pins TPINP and TPINN. The input is differential with the common mode voltage internally set. At the start of packet reception from the twisted pair link, no more than 5 bits are received from the twisted pair cable and not transmitted. The first bit sent at the optical transmitter may contain phase violations or invalid data, but all subsequent bits are valid.The TP squelch will reject the following signals on the TPINP and TPINN inputs:1.All signals that produce a peak magnitude lessthan 300mV (450mV typical).2. All continuous sinusoidal signals of amplitude lessthan 6.2V P–P and frequency less than 2MHz.3.All single sinusoidal cycles of amplitude less than6.2V P–P and either polarity, where the frequency isbetween 2MHz and 15MHz. For a period of 4 BTbefore and after this single cycle, the signal willconform to (1) above.4.All sinusoidal cycles gated by a 100ns pulse gate ofamplitude less than 6.2V P–P and either polarity, where the sinusoidal frequency is between 2MHz and30MHz. The off time of the pulse gate on thesinusoidal signal shall be at least 400ns.The first three receive squelch criteria are required to conform to the 10BASE-T standard. The fourth receive squelch criteria exceeds the 10BASE-T requirements and enhances performance. The fourth squelch criteria prevents a false unsquelch caused by cross talk or noise typically found coupling from the phone lines onto the receive twisted pair.After the TP inputs are unsquelched, the detection threshold is lowered to 225mV. Upon passing the TP squelch requirements the receive data passes to the LED Driver. The addition of jitter through the TP to OP path is no more than ±1.5ns.While in the unsquelch state, the TP squelch circuit looks for the start of idle signal at the end of the packet. When start of idle is detected, TP squelch is turned on again. The proper start of idle occurs when the input signal remains above 300mV for 160ns.LINK TEST FUNCTIONTransmission — Whenever data is not being delivered to the twisted pair link, the idle signal is applied. The idle signal is a sequence of Link Pulses separated by a 16ms period of silence. The idle signal starts with a period of silence after a packet transmission ends. The link test pulse is a single high pulse with the same amplitude requirements as the data signal.Reception — The transceiver monitors the receive twisted pair input for packet and link pulse activity. If neither a packet nor a link test pulse is received for 50 to 150ms, the transceiver enters the Link Test Fail state and inhibits transmission and reception. Link pulses received with the wrong polarity will be ignored and cause the chip to go into link test fail.When a packet, or five consecutive link test pulses is received from the twisted pair input, the transceiver will exit the Link Test Fail state upon transmit and receive data being idle, and re-enable transmission and reception.元器件交易网ML4664/ML4669Link test pulses that do not occur within at most 25 to 150ms of each other are not considered consecutive.In addition, detected pulses that occur within a time between 2 to 7ms of a previous pulse will be considered as noise by the link test circuitry, and will reset the count of consecutive link pulses to zero.If the ML4664 enters the link test fail state, both link pulses at the twisted pair transmitter, and idle at theoptical transmitter will continue to be sent. Data will not be sent at either transmitter.If the ML4669 enters the link test fail state, idle will not be sent at the optical transmitter. Data will not be sent at either transmitter. However, link pulses may still be sent at the twisted pair transmitter, depending on the optical inputs. See Table 1.POLARLITY CIRCUITRYThe ML4664/ML4669 offers automatic polarity correction.The POLDIS pin is used to report the status of the receive pair polarity. This pin is high when the polarity is correct,and low when the polarity is reversed. If this pin is grounded, the polarity correction circuit is disabled.Polarity Detection — The internal circuitry uses the start of idle signal to determine the receive polarity. With the correct receive polarity, the Start of Idle signal (the end of the frame) will remain above 300mV for more than 160ns. If the polarity is reversed, the Start of Idle signal will end with a negative voltage.The POLDIS status pin is updated only when fourconsecutive frames are received with the same Start of Idle polarity. In the case where the part is powered up with the receive polarity reversed and no frames are received, the part will go into link test fail withoutreflecting a reverse polarity condition. If five consecutive revised link pulses are then received, the polarity will reverse and the device will come out of Link Test Fail.TP TRANSMISSIONThe TP transmit function consists of detecting thepresence of data from the OP inputs, OPINP and OPINN and driving that data onto the transmit twisted pair(TPOUTP , TPOUTN). A positive signal on the OPINP lead relative to the OPINN lead will result in a positive signal on the TPOUTP lead of the chip with respect to the TPOUTN lead.Before data will be transmitted onto the twisted pair from the OP inputs, it must exceed the squelch requirements for the OP inputs. The OP squelch circuit serves the function of preventing any noise from being transmitted onto the twisted pair.The output stage of the transmitter is a current mode switch which develops the output voltage by driving current through the terminating resistor and the output filter. The transmitter employs a center tap 2:1 transformer where the center tap is tied to V CC (+5V). While one pin of the transmit pair (TPOUTP , TPOUTN) is pulled low, the other pin floats. The output pins to the twisted pair wires,Figure 9. Transmit Pre-Equalization WaveformBINARY TxTP+TxTP–OUTPUT AFTER TRANSMIT FILTERINPUT INTO RECEIVER011100110SYSTEM DESCRIPTION (Continued)元器件交易网TPOUTP and TPOUTN, can drive a 100W, 150W load, or a variety of impedances that are characteristic of the twisted pair wire. RTSETTP selects the current into the TPOUTP, TPOUTN pins. This current along with the characteristic impedance of the cable determines the output voltage.Once the characteristic impedance of the twisted pair is determined, one must select the appropriate RTSETTP resistor as well as match the terminating impedances of the transmit and receive filter. The RTSETTP resistor can be selected as follows:RTSETTPR L=100220W(2)Where R L is the characteristic impedance of the twisted pair cable.The transmitter incorporates a pre-equalization circuit for driving the twisted pair line. Pre-equalization compensates for the amplitude and phase distortion introduced by the twisted pair cable. The twisted pair line will attenuate the 10MHz signal more than the 5MHz signal. Therefore pre-equalization insures that both the 5 and 10MHz components will be roughly the same amplitude at the far end receiver.The pre-equalization circuit reduces the current output when a 5MHz bit is being transmitted. After 50ns of a5MHz bit, the current level is reduced to approximately 2/3 of its peak for the remaining 50ns. Figure 9 illustrates the pre-equalization.An on-chip one-shot determines the pulse width of the pre-equalized transmit signal. This requires an external capacitor connected to pins TxCAP0 and TxCAP1. The proper value for this one-shot is 680pF. Pre-equalization can be disabled by shorting TxCAP0 and TxCAP1 together.The transmitter enters the idle state when it detects start of idle on OPINP and OPINN input pins. The transmitter maintains a minimum differential output voltage of at least 450mV for 250ns after the last low to high transition. The driver differential output voltage will then be within 50mV of 0V within 45 bit times.OP SQUELCHThe input to the optical receiver comes from a fiber optic pre-amp. At the start of packet reception no more than 2.7 bits are received from the fiber cable and not transmitted onto the TP outputs. The receive squelch will reject frequencies lower than 2.51MHz.While in the unsquelch state, the receive squelch circuit looks for the start of idle signal at the end of the packet. Start of idle occurs when the input signal remains idle for more than 160ns. When start of idle is detected, the receive squelch circuit returns to the squelch state and the start of idle signal is output on the twisted pair outputs TPOUTP, TPOUTN.INPUT AMPLIFIERThe OPINP, OPINN input signal is fed into a limiting amplifier with a gain of about 100 and input resistance of 1.3k W. Maximum sensitivity is achieved through the use of a DC restoration feedback loop and AC coupling the input. When AC coupled, the input DC bias voltage is set by an on-chip network at about 1.7V. These coupling capacitors, in conjunction with the input impedance of the amplifier, establish a high pass filter with 3dB corner frequency, f L, at:f=12CL p 1300(3)Since the amplifier has a differential input, two capacitors of equal value are required. If the signal driving the input is single ended, one of the coupling capacitors can be tied to AV CC.The internal amplifier has a lowpass filter built-in to band limit the input signal which in turn will improve the signal to noise ratio.Although the input is AC coupled, the offset voltage within the amplifier will be present at the amplifier’s output. In order to reduce this error a DC feedback loop is incorporated. This negative feedback loop nulls the offset voltage, forcing V OS to be zero. Although the capacitor on V DC is non-critical, the pole it creates can effect the stability of the feedback loop. To avoid stability problems, the value of this capacitor should be at least 10 times larger than the input coupling capacitors.The comparator is a high-speed differential zero crossing detector that slices and accurately digitizes the receive signal. The output of the comparator is fed into the receive squelch circuit.SYSTEM DESCRIPTION (Continued)1112OPTICAL LINK DETECT CIRCUIT AND LOW LIGHTThe link detect circuit monitors the input signal and determines when the input falls below a preset voltage level. When the input falls below a preset voltage, the ML4664/ML4669 goes into the Low Light state. In the Low Light state the TP transmitter is disabled, but continues sending link pulses, the receiver is disabled, and the LMON LED pin goes to high shutting off the LMON LED. To return to the Link Pass state, the optical receiver power must be 20% higher than the shut-off state. This built-in hysteresis adds stability to the Link Monitor circuit. Once the receiver power threshold is exceeded, the ML4664/ML4669 waits 250ms to 750ms, then checks to see that no data is being received before re-enabling the transmitter, and receiver, and lighting up the LMON LED.When the ML4664 is in the low light state, both the link pulses at the twisted pair transmitter and idle at the optical transmitter continue to be sent. However, when the ML4669 is in the low light state, link pulses are not sent at the twisted pair transmitter. Data is not sent at either transmitter. An idle signal may be sent at the optical transmitter, depending on the twisted pair inputs. See Table 1.The V THADJ pin is used to adjust the sensitivity of the receiver. The ML4664/ML4669 is capable of exceeding the 10BASE-FL specifications for sensitivity. The sensitivity is dependent on the layout of the PC board. A good low noise layout will exceed the 10BASE-FL specifications, while a poor layout will fail to meet the sensitivity and BER spec.The threshold generator shifts the reference voltage atV THADJ through a circuit which has a temperature coefficient matching that of the limiting amplifier. The relationship between the V THADJ and the V TH (the peak to peak input threshold) is:V VTHADJ TH=408(4)A 10BASE-FL receiver must make less than 1 x 10–9 bit errors at a receive power level of –32.5dBm average. One procedure to determine the sensitivity of a receiver is to start at the lowest optical power level and gradually increase the optical power until the BER is met. In this case the Link Detect circuit must not disable the receiver (i.e. V THADJ should be tied to 1.0V). Once the sensitivity of the receiver is determined, V THADJ can be set just above the power level that meets the BER specification. This way the receiver will shut-off before the BER is exceeded.For 10BASE-FL V THADJ can be tied directly to V REF. However if greater sensitivity is required the circuit in Figure 10 can be used to adjust the V THADJ voltage. Even if V REF is tied to V THADJ, it is a good idea to layout a board with these two resistors available. This will allow potential future adjustments without board revisions.The response time of the Link Detect circuit is set by the C TIMER pin. Starting from the link off state the link can be switched on if the input exceeds the set threshold for a time given by:T=C TIMER 0.7VA700m(5) To switch the link from on to off, the above time will be doubled. A value of 0.05µF will meet to 10BASE-FL specifications.LED DRIVERSThe ML4664/ML4669 has five LED drivers. The LED driver pins are active low, and the LEDs are normally off (except for LTF and LMON). The LEDs are tied to their respective pins through a 300W resistor to 5 Volts.The OPLED and TPLED pins have pulse stretchers on them which enables the LEDs to be visible. If another event occurs before the timer expires, the LED timer will reset and restart the timing. Therefore rapid events will leave the LEDs continuously on. The LMON, LTF, and POLDIS LEDs do not have a pulse stretcher on since its condition occurs long enough for the eye to see.LOW LIGHT CONDITIONThe LMON LED output is used to indicate a low light condition. LMON is activated low when both the receive power exceeds the Link Monitor threshold and there are transitions on OPINP, OPINN less than 3µs apart. If either one of these conditions do not exist, LMON will go high.SYSTEM DESCRIPTION (Continued)13。

MAX266中文数据手册

MAX266中文数据手册MAX266/265中文数据手册By Hi_Cracker @whu引脚电阻可编程通用高效滤波器-----MAX266/265General Description和MAX265是高效的容滤波器，专门设计用于需要高精度滤波的应用MAX266场合。

内置了两个独立的滤波模块，可以配置成低通，高通，带通，带阻，全通滤波器。

中心频率或者截止频率的控制需要外接电阻以及6 Pin-Strapped 的输入特性来编程实现，然而，Q值仅用电阻连接实现。

各种各样类型的滤波器都可以实现（巴特沃斯，切比雪夫，椭圆滤波器等等）。

内部集成了两个运算放大器。

MAX265可以将中心/截止频率可以最高调到40Khz，然而，MAX266，通过使用一个低范围的fclk/fo比例系数，可以将fos 调到140Khz。

4MHZ系统时钟，可以通过一个晶振或是额外的源获得。

滤波器的操作电压为从±2.37v到±6.3v或者+5V的单电源供电。

Application：声纳电子设备Anti-Aliasing 滤波器数字信号处理震动音频分析远程通信测试仪器Features滤波器参数设置软件化256bit的频率控制字电阻调整Q值和fo140Khz频率调节范围±5V或者单电源﹢5V操作电压Introduction每个MAX266/265都包含的两个可配置滤波器模块已经显示在数据手册前面的功能框图上。

fclk/fo编程输入（F0-F5）被两个滤波模块共用,然而，每个部分的fo仍然受到各自外接电阻的独立调节。

各个模块的的Q值也是受到各自的外接电阻的独立调节的。

MAX266使用比MAX265更低范围的取样比率（fclk/fo），这样就可以产生更高的信号带宽以及fo的可编程范围。

降低fclk/fo产生的影响主要就是比MAX265的滤波器参数的连续性稍微差了一些，但是这些不同可以通过使用图23所示的图形或是美信得滤波器软件来补偿。

They have two sup-ply pins: V CC and GND. V CC and GND are used to drive the internal CMOS switches and set the limits of the ana-log voltage on any switch. Reverse ESD-protection diodes are internally connected between each analog-signal pin and both V CC and GND. If any analog signal exceeds V CC or GND, one of these diodes conducts.During normal operation, these and other reverse-biased ESD diodes leak, forming the only current drawn from V CC or GND.Virtually all the analog leakage current comes from the ESD diodes. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V CC or GND and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V CC and GND pins con-stitutes the analog-signal-path leakage current. All ana-log leakage current flows between each pin and one of the supply terminals, not to the other switch terminal.This is why both sides of a given switch can show leak-age currents of either the same or opposite polarity.V CC and GND power the internal logic and set the input logic limits. Logic inputs have ESD-protection diodes to ground.in both directions.Pin DescriptionMAX4617/MAX4618/MAX4619High-Speed, Low-Voltage, CMOS AnalogMultiplexers/Switches_______________________________________________________________________________________9The logic-level thresholds are TTL/CMOS compatible when V CC is +5V. As V CC rises, the threshold increas-es; as V CC falls, the threshold decreases. For example,when V CC = +3V the guaranteed minimum logic-high threshold decreases to 2.0VPower SupplyThese devices operate from a single supply between +2.5V and +5.5V. All of the bipolar precautions must be observed. At room temperature, they actually “work”with a single supply near or below +2V, although as supply voltage decreases, switch on-resistance becomes very high.Overvoltage ProtectionProper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings because stresses beyond the listed rat-ings can cause permanent damage to the devices.Always sequence V CC on first, followed by the logic inputs and analog signals. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure 1).Adding diodes reduces the analog-signal range to one diode drop below V CC and one diode drop above GND, but does not affect the devices’ low switch resis-tance and low leakage characteristics. Device opera-tion is unchanged, and the difference between V CC and GND should not exceed 6V. These protection diodes are not recommended if signal levels must extend to ground.High-Frequency PerformanceIn 50Ωsystems, signal response is reasonably flat up to 50MHz (see Typical Operating Characteristics ).Above 20MHz, the on-response has several minor peaks that are highly layout dependent. The problem is not turning the switch on, but turning it off. The off-state switch acts like a capacitor and passes higher frequen-cies with less attenuation. At 10MHz, off-isolation is about -50dB in 50Ωsystems, becoming worse (approx-imately 20dB per decade) as frequency increases.Higher circuit impedances also degrade off-isolation.Adjacent channel attenuation is about 3dB above that of a bare IC socket and is entirely due to capacitive coupling.Pin NomenclatureThe MAX4617/MAX4618/MAX4619 are pin compatible with the industry-standard 74HC4051/74HC4052/74HC4053 and the MAX4581/MAX4582/MAX4583. In single-supply applications, they function identically and have identical logic diagrams, although these parts dif-fer electrically.The pin designations and logic diagrams in this data sheet conform to the original 1972 specifications pub-lished by RCA for the CD4051/CD4052/CD4053. These designations differ from the standard Maxim switch and mux designations found on other Maxim data sheets (including the MAX4051/MAX4052/MAX4053) and may cause confusion. Designers who feel more comfortable with Maxim’s standard designations are advised that the pin designations and logic diagrams on the MAX4051/MAX4052/MAX4053 data sheet may be freely applied to the MAX4617/MAX4618/MAX4619.Figure 1.
