Its intuitive Windows-like GUI ensures a fast learning curve. Plus, its new and improved OTDR 2 environment offers icon-based functions, instant boot-up, automatic macrobend finders as well as improved auto and real-time modes.The MaxTester 700B/C Series is a line of genuine high-performance OTDRs from the world’s leading manufacturer. It delivers EXFO’s tried and true OTDR quality and accuracy along with the best optical performance for right-first-time results, every time. The amazing 12-hour battery life will never let a technician down, and the plug-and-play hardware options, like the VFL, power meter and USB tools, make every technician’s job easier.Most importantly, the MaxTester 700B/C Series is finally bringing the intelligent Optical Link Mapper (iOLM), an intelligent OTDR-based application, to the handheld market. This advanced software turns even the most complex trace analysis into a simple, one-touch task.Ultimately, the MaxTester 700B/C Series is small enough to fit in your hand and big enough to fit all your needs!THE ENTRY-LEVEL SOLUTION DESIGNED FOR ALL YOUR TESTING NEEDSThe MaxTester 730C PON/metro OTDR is optimized to test through optical splitters up to 1x128, ensuring complete end-to-end FTTH characterization.

Other models available:•MaxTester 715B short access and FTTx last-mile installation and troubleshooting•MaxTester 720C LAN/WAN access OTDR—optimized for multimode and singlemode access network construction and troubleshooting SECURE YOUR INVESTMENT AGAINST THEFTProtected instruments have no value on the black market making them completely unappealing to thieves.With our security management option, administrators can define and load a tamper-proof security profileon the MaxTester, displaying a property message on the home screen and securing it with a user password(permanent or renewable).LOOKING FOR ICON-BASED MAPPING?Linear view (included on all EXFO OTDRs)Available on our OTDRs since 2006, the linear view simplifies the reading of an OTDR trace by displaying icons in a linear way for each wavelength. This view converts the graph data points obtained from a traditional single pulse trace into reflective, non-reflective or splitter icons. With applied pass/fail thresholds, it becomes easier to pinpoint faults on your link.This improved linear view offers you the flexibility to display both theOTDR graph and its linear view without having to perform a toggleto analyze your fiber link.Although this linear view simplifies OTDR interpretation of a singlepulse-width trace, the user must still set the OTDR parameters.In addition, multiple traces must often be performed in order tofully characterize the fiber links. See the section below to learnabout how the iOLM can perform this automatically and with moreaccurate results.OTDR testing comes withits load of challenges...In response to these challenges, EXFO developed a better way to test fiber optics:application designed to simplify OTDR testing by eliminating the need to configure parameters, and/or analyze and interpret multiple complex OTDR traces. Its advanced algorithms dynamically define the testing parameters, as well as the number of acquisitions that best fit the network under test. By correlating multipulse widths on multiple wavelengths, the iOLM locates and identifiesIn addition to the standard iOLM feature set, you can select added-value features as part of the Order a unit with the iOLM application onlyCOMBORun both iOLM and OTDR applications (Oi code)Add the iOLM software option to your iOLM-ready unit, even while in the fieldGET THE BEST OUT OF YOUR DATA POST-PROCESSING— ONE SOFTWARE DOES IT ALLThis powerful reporting software is the perfect complement to your OTDR, and can be used to create and customize reports to fully address your needs.OPTICAL PLUG-AND-PLAY OPTIONSThe MaxTester features plug-and-play optical options that can be purchased whenever you need them: at the time of your order or later on. In either case, installation is a snap, and can be performed by the user without the need for any software update. Optical power meterEXFO’s high-level power meter (GeX) can measure up to 27 dBm, the highest in the industry. This is essential for hybrid fiber-coaxial (HFC) networks or high-power signals. If used with an auto-lambda/auto-switching compatible light source, the power meter automatically synchronizes on the same wavelength, thus avoiding any risk of mismatched measurement.•Extensive range of connectors•Auto-lambda and auto-switching•Offers measurement storage and reporting•Seven standard calibrated wavelengthsVisual fault locator (VFL)The plug-and-play VFL easily identifies breaks, bends, faulty connectors and splices, in addition to other causes of signal loss. This basic, yet essential troubleshooting tool should be part of every field technician’s toolbox. The VFL visually locates and detects faults over distances of up to 5 km by creating a bright-red glow at the exact location of the fault on singlemode or multimode fibers (available with the optical power meter only).FIBER CONNECTOR INSPECTION AND CERTIFICATION–THE ESSENTIAL FIRST STEP BEFORE ANY OTDR TESTING Taking the time to properly inspect a fiber-optic connector using an EXFO fiber inspection scope can prevent a host of issues from arising further down the line, thus saving you time, money and trouble. Moreover, using a fully automated solution with autofocus capabilities will turn this critical inspection phase into a fast and hassle-free one-step process.Did you know that the connector of your OTDR/iOLM is also critical?The presence of a dirty connector at an OTDR port or launch cable can negatively impact your test results, and even cause permanent damage during mating. Therefore, it is critical to regularly inspect these connectors to ensure that they are free of any contamination. Making inspection the first step of your OTDR best practices willmaximize the performances of your OTDR and your efficiency.PACKAGED FOR EFFICIENCY1Singlemode OTDR port610/100 Mbit/s Ethernet port11 2Singlemode Live OTDR port7Two USB 2.0 ports12 3Stylus8AC adapter13 4Power meter9Home/switch application andscreen capture (hold)5Visual fault locator10Power on/off/stand by123456789101113SOFTWARE UTILITIESSoftware update Ensure that your MaxTester is up-to-date with the latest software.VNC configuration The Virtual Network Computing (VNC) utility allows technicians to easily remote control the unit via a computer or laptop.

The charge pumps operate in a discontinuous mode; if the output voltages are less than 5.5V, the charge pumps are enabled, and if the output voltages exceed 5.5V, the charge pumps are disabled. Each charge pump requires a flying capacitor (C1, C2) and a reservoir capacitor (C3, C4) to generate the V+ and V- supplies.RS-232 TransmittersThe transmitters are inverting level translators that con-vert CMOS-logic levels to 5.0V EIA/TIA-232 levels.The MAX3222/MAX3232/MAX3241 transmitters guaran-tee a 120kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF, providing compatibility with PC-to-PC communication software (such as LapLink™).Typically, these three devices can operate at data rates of 235kbps. Transmitters can be paralleled to drive multi-ple receivers or mice.The MAX3222/MAX3237/MAX3241’s output stage is turned off (high impedance) when the device is in shut-down mode. When the power is off, the MAX3222/MAX3232/MAX3237/MAX3241 permit the outputs to be driven up to ±12V.The transmitter inputs do not have pullup resistors.Connect unused inputs to GND or V CC .MAX3237 MegaBaud OperationIn normal operating mode (MBAUD = G ND), the MAX3237 transmitters guarantee a 250kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF.This provides compatibility with PC-to-PC communica-tion software, such as Laplink.For higher speed serial communications, the MAX3237features MegaBaud operation. In MegaBaud operating mode (MBAUD = V CC ), the MAX3237 transmitters guar-antee 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 MAX3237 transmitters guarantee a 1Mbps data rate into worst-case loads of 3k Ωin parallel with 1000pF.Figure 1.

The MAX3222/MAX3237/MAX3241 receivers have inverting three-state outputs. In shutdown, the receivers can be active or inactive (Table 1).The complementary outputs on the MAX3237 (R1OUTB)and the MAX3241 (R1OUTB, R2OUTB) are always active,regardless of the state of EN or SHDN . This allows for Ring Indicator applications without forward biasing other devices connected to the receiver outputs. This is ideal for systems where V CC is set to 0V in shutdown to accommodate peripherals, such as UARTs (Figure 2).MAX3222/MAX3237/MAX3241Shutdown ModeSupply current falls to less than 1µA in shutdown mode (SHDN = low). When shut down, the device’s charge pumps are turned off, V+ is pulled down to V CC , V- is pulled to ground, and the transmitter outputs are dis-abled (high impedance). The time required to exit shut-down is typically 100µs, as shown in Figure 3. Connect SHDN to V CC if the shutdown mode is not used. SHDN has no effect on R_OUT or R_OUTB.MAX3222/MAX3237/MAX3241Enable ControlThe inverting receiver outputs (R_OUT) are put into a high-impedance state when EN is high. The complemen-tary outputs R1OUTB and R2OUTB are always active,regardless of the state of EN and SHDN (Table 1). EN has no effect on T_OUT.__________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, refer to Table 2 for required capacitor values. Do not use values lower than those listed in Table 2. Increasing the capaci-tor values (e.g., by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consump-tion. C2, C3, and C4 can be increased without changing C1’s value. However, do not increase C1 without also increasing the values of C2, C3, and C4, to maintain the proper ratios (C1 to the other capacitors).When using the minimum required capacitor values,make sure the capacitor value does not degrade exces-sively with temperature. If in doubt, use capacitors with a higher nominal value. The capacitor’s equivalent series resistance (ESR), which usually rises at low tempera-tures, influences the amount of ripple on V+ and V-.Figure 2.

In applications that are sensitive to power-supply noise, decouple V CC to ground with a capacitor of the same value as charge-pump capacitor C1. Connect bypass capacitors 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 whenExiting ShutdownFigure 3 shows two transmitter outputs when exiting shutdown mode. As they become active, the two trans-mitter outputs are shown going to opposite RS-232 lev-els (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 MAX3241 has been specifically designed to power serial mice while operating from low-voltage power sup-plies. It has been tested with leading mouse brands from manufacturers such as Microsoft and Logitech. The MAX3241 successfully drove all serial mice tested and met their respective current and voltage requirements.Figure 4a shows the transmitter output voltages under increasing load current at 3.0V.

The circuit features 200nA input-referred noise, 920MHz bandwidth, and 1mA input overload. The MAX3267 provides a pin-for-pin compatible solu-tion for communications up to 2.5G bps. It features 500nA input-referred noise, 1.9G Hz bandwidth, and 1mA input overload.Both devices operate from a +3.0V to +5.5V single sup-ply and require no compensation capacitor. They also include a space-saving filter connection that provides positive bias for the photodiode through a 1.5k Ωresistor to V CC . These features allow easy assembly into a TO-46or TO-56 header with a photodiode.The 1.25G bps MAX3266 has a typical optical dynamic range of -24dBm to 0dBm in a shortwave (850nm)configuration or -27dBm to -3dBm in a longwave (1300nm) configuration. The 2.5G bps MAX3267 has a typical optical dynamic range of -21dBm to 0dBm in a shortwave configuration or -24dBm to -3dBm in a long-wave configuration.ApplicationsGigabit Ethernet1Gbps to 2.5Gbps Optical Receivers Fibre ChannelFeatureso 200nA Input-Referred Noise (MAX3266)500nA Input-Referred Noise (MAX3267)o 920MHz Bandwidth (MAX3266)1900MHz Bandwidth (MAX3267)o 1mA Input Overloado +3.0V to +5.5V Single-Supply VoltageMAX3266/MAX3267, Low-NoiseTransimpedance Preamplifiers for LANs________________________________________________________________Maxim Integrated Products 1Typical Application Circuit*Dice are designed to operate over a -40°C to +140°C junction tem-perature (Tj) range, but are tested and guaranteed at T A = +25°C.Pin ConfigurationOrdering InformationFor free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.M A X 3266/M A X 32671.25Gbps/2.5Gbps, +3V to +5.5V , Low-Noise Transimpedance Preamplifiers for LANs 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—MAX3266C/MAX3267C(V CC = +3.0V to +5.5V, T A = 0°C to +70°C, 100Ωload between OUT+ and OUT-.

Figure 2 is a func-tional diagram of the MAX3266, which comprises a trans-impedance amplifier, a voltage amplifier, an output buffer, an output filter, and a DC cancellation circuit.The MAX3267, a transimpedance amplifier designed for 2.5G bps fiber optic applications, shares similar architecture with the MAX3266.Transimpedance AmplifierThe signal current at the input flows into the summing node of a high-gain amplifier. Shunt feedback through R F converts this current to a voltage with gain of approx-imately 2.2k Ω(1.0k Ωfor MAX3267). Schottky diodes clamp the output voltage for large input currents, as shown in Figure 3.Voltage AmplifierThe voltage amplifier converts single-ended signals to differential signals and introduces a voltage gain.Output BufferThe output buffer provides a reverse-terminated volt-age output. The buffer is designed to drive a 100Ωdif-ferential load between OUT+ and OUT-. The output current is divided between internal 50Ωload resistors and the external load resistor. In the typical operating circuit, this creates a voltage-divider with gain of 1/2.The MAX3266 can also be terminated with higher out-put impedances, which increases gain and output volt-age swing.For optimum supply-noise rejection, the MAX3266should be terminated with a differential load. If a single-ended output is required, the unused output should be similarly terminated. The MAX3266 will not drive a DC-coupled, 50Ωgrounded load.Figure 2. MAX3266 Functional Diagram Figure 1. Typical Photodiode Capacitance vs. Bias VoltageMAX3266/MAX32671.25Gbps/2.5Gbps, +3V to +5.5V , Low-NoiseTransimpedance Preamplifiers for LANs_______________________________________________________________________________________7Output FilterThe MAX3266 includes a one-pole lowpass filter that limits the circuit bandwidth and improves noise perform-ance.DC Cancellation CircuitThe DC cancellation circuit uses low-frequency feed-back to remove the DC component of the input signal (Figure 4). This feature centers the input signal within the transimpedance amplifier’s linear range, thereby reducing pulse-width distortion on large input signals.The DC cancellation circuit is internally compensated and therefore does not require external capacitors. This circuit minimizes pulse-width distortion for data sequences that exhibit a 50% duty cycle. A duty cycle significantly different from 50% will cause the MAX3266to generate pulse-width distortion.DC cancellation current is drawn from the input and creates noise. For low-level signals with little or no DC component, this is not a problem. Amplifier noise will increase for signals with significant DC component (see Typical Operating Characteristics ).Applications InformationOptical Power RelationsMany of the MAX3266 specifications relate to the inputsignal amplitude. When working with fiber optic receivers, the input is usually expressed in terms of aver-age optical power and extinction ratio. Figure 5 showsrelations that are helpful for converting optical power to input signal when designing with the MAX3266. Optical power relations are shown in Table 1; the defini-tions are true if the average duty cycle of the input data is 50%.Optical Sensitivity CalculationThe input-referred RMS noise current (I N ) of the MAX3266 generally determines the receiver sensitivity.To obtain a system bit error rate (BER) of 1E-12, the SNR ratio must always exceed 14.1. The input sensitivi-Where ρis the photodiode responsivity in A/W.Input Optical OverloadThe overload is the largest input that the MAX3266accepts while meeting specifications. The optical over-load can be estimated in terms of average power with the following equation:Figure 3. MAX3266 Limited Output Figure 4. DC Cancellation Effect on InputM A X 3266/M A X 32671.25Gbps/2.5Gbps, +3V to +5.5V , Low-Noise Transimpedance Preamplifiers for LANs 8_______________________________________________________________________________________Optical Linear RangeThe MAX3266 has high gain, which limits the output when the input signal exceeds 30µAp-p (40µAp-p for MAX3267). The MAX3266 operates in a linear range for inputs not exceeding:Layout ConsiderationsUse good high-frequency design and layout tech-niques. The use of a multilayer circuit board with sepa-rate ground and power planes is recommended.Connect the G ND pins to the ground plane with the shortest possible traces.Noise performance and bandwidth will be adversely affected by capacitance at the IN pin. Minimize capaci-tance on this pin and select a low-capacitance photodi-ode. Assembling the MAX3266 in die form using chip and wire technology provides the best possible perform-ance. Figure 6 shows a suggested layout for a TO header.The SO package version of the MAX3266 is offered as an easy way to characterize the circuit and become familiar with the circuit’s operation, but it does not offer optimum performance. When using the SO version of the MAX3266, the package capacitance adds approxi-mately 0.3pF at the input. The PC board between the MAX3266 input and the photodiode also adds parasitic capacitance. Keep the input line short, and remove power and ground planes beneath it.Photodiode FilterSupply voltage noise at the cathode of the photodiode produces a current I = C PD ∆V/∆t, which reduces the receiver sensitivity (C PD is the photodiode capaci-tance.) The filter resistor of the MAX3266, combined with an external capacitor, can be used to reduce this noise (see the Typical Application Circuit ). Current gen-erated by supply noise voltage is divided between C FILTER and C PD . The input noise current due to supply noise is (assuming the filter capacitor is much larger than the photodiode capacitance):I NOISE = (V NOISE )(C PD ) / (R FILTER )(C FILTER )If the amount of tolerable noise is known, the filter capacitor can be easily selected:C FILTER = (V NOISE )(C PD ) / (R FILTER )(I NOISE )For example, with maximum noise voltage = 100mVp-p,C PD = 0.85pF, R FILTER = 1.5k Ω, and I NOISE selected to be 100nA (1/2 of the MAX3266’s input noise):C FILTER = (100mV)(0.85pF) / (1500Ω)(100nA) = 570pFWire BondingFor high current density and reliable operation, the MAX3266 uses gold metalization. Connections to the die should be made with gold wire only, using ball-bonding techniques. Wedge bonding is not recom-mended. Die thickness is typically 15mils (0.375mm).Figure 5.

The enhanced ESD structure protects all transmitter outputs and receiver inputs to ±15kV using IEC 1000-4-2 Air-G ap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge (±9kV for MAX3246E), and ±15kV using the Human Body Model. The logic and receiver I/O pins of the MAX3237E are protected to the above standards, while the transmit-ter output pins are protected to ±15kV using the Human Body Model.A proprietary low-dropout transmitter output stage delivers true RS-232 performance from a +3.0V to +5.5V power supply, using an internal dual charge pump. The charge pump requires only four small 0.1µF capacitors for opera-tion from a +3.3V supply. Each device guarantees opera-tion at data rates of 250kbps while maintaining RS-232output levels. The MAX3237E guarantees operation at 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode, while maintaining RS-232-compliant output levels.The MAX3222E/MAX3232E have two receivers and two transmitters. The MAX3222E features a 1µA shutdown mode that reduces power consumption in battery-pow-ered portable systems. The MAX3222E receivers remain active in shutdown mode, allowing monitoring of external devices while consuming only 1µA of supply current. The MAX3222E and MAX3232E are pin, package, and func-tionally compatible with the industry-standard MAX242and MAX232, respectively.The MAX3241E/MAX3246E are complete serial ports (three drivers/five receivers) designed for notebook and subnotebook computers. The MAX3237E (five drivers/three receivers) is ideal for peripheral applications that require fast data transfer. These devices feature a shut-down mode in which all receivers remain active, while consuming only 1µA (MAX3241E/MAX3246E) or 10nA (MAX3237E).The MAX3222E, MAX3232E, and MAX3241E are avail-able in space-saving SO, SSOP, TQFN and TSSOP pack-ages.

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 ±5V EIA/TIA-232-compli-ant levels.The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E 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 par-alleled to drive multiple receivers or mice.The MAX3222E/MAX3237E/MAX3241E/MAX3246E transmitters are disabled and the outputs are forcedinto a high-impedance state when the device is in shut-down mode (SHDN = G ND). The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E permit the outputs to be driven up to ±12V in shutdown.The MAX3222E/MAX3232E/MAX3241E/MAX3246E transmitter inputs do not have pullup resistors. Connect unused inputs to GND or V CC . The MAX3237E’s trans-mitter 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/MAX3246E receivers have inverting three-state outputs.Drive EN high to place the receiver(s) into a high-impedance state. Receivers can be either active or inactive in shutdown (Table 1).Figure 1. Slew-Rate Test CircuitsLapLink is a trademark of Traveling Software.M A X 3222E /M A X 3232E /M A X 3237E /M A X 3241E †/M A X 3246EUp to 1Mbps, True RS-232 Transceivers10______________________________________________________________________________________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 indicator applications without forward biasing other devices connected to the receiver outputs. This is ideal for systems where V CC drops to zero in shutdown to accommodate peripherals such as UARTs (Figure 2).MAX3222E/MAX3237E/MAX3241E/MAX3246E Shutdown 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 out-puts 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 shutdown 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/MAX3246E have extra protection against static electricity. Maxim’s engineers have developed state-of-the-art structures to protect 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 applications.SHDN T2OUTT1OUT5V/div2V/divV CC = 3.3V C1–C4 = 0.1μFFigure 3.

This model consists of a 100pF capacitor charged to the ESD voltage of interest,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 performance of finished equipment; it does not specifi-cally refer to integrated circuits. The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E 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. The Contact Discharge method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. 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.Table 2. Required Minimum Capacitor ValuesFigure 6a. MAX3241E Transmitter Output Voltage vs. Load Current Per TransmitterTable 3. Logic-Family Compatibility with Various Supply VoltagesMAX3222E/MAX3232E/MAX3237E/MAX3241E †/MAX3246EUp to 1Mbps, True RS-232 TransceiversApplications 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 2 for 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).When using the minimum required capacitor values,make sure the capacitor value does not degradeexcessively with temperature. 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 sensitive to power-supply noise, use a capacitor of the same value as charge-pump capacitor C1. Connect bypass capacitors as close to the IC as possible.Operation Down to 2.7VTransmitter outputs meet EIA/TIA-562 levels of ±3.7V with supply voltages as low as 2.7V.Figure 6b.

As they become active, the two trans-mitter 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 undesir-able transients as they come out of shutdown. Note thatthe transmitters are enabled only when the magnitude of V- exceeds approximately -3.0V.Mouse DrivabilityThe MAX3241E is designed to power serial mice while operating from low-voltage power supplies. It has been tested with leading mouse brands from manu-facturers such as Microsoft and Logitech. The MAX3241E successfully drove all serial mice tested and met their current and voltage requirements.MAX3222E/MAX3232E/MAX3237E/MAX3241E †/MAX3246EUp to 1Mbps, True RS-232 TransceiversFigure 6a shows the transmitter output 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/MAX3246E maintain the RS-232 ±5V minimum transmit-ter output voltage even at high data rates. Figure 7shows a transmitter loopback test circuit. Figure 8shows a loopback test result at 120kbps, and Figure 9shows the same test at 250kbps. For Figure 8, all trans-mitters were driven simultaneously at 120kbps into RS-232 loads in parallel with 1000pF. For Figure 9, a single transmitter was driven at 250kbps, and all transmitters were loaded with an RS-232 receiver in parallel with 1000pF.The MAX3237E maintains the RS-232 ±5.0V minimum transmitter output voltage at data rates up to 1Mbps.Figure 10 shows 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/MAX3246E can directly interface with various 5V logic families, including ACT and HCT CMOS. See Table 3for more information on possible combinations of inter-connections.UCSP ReliabilityThe UCSP represents a unique packaging form factor that may not perform equally to a packaged product through traditional mechanical reliability tests. UCSP reliability is integrally linked to the user’s assembly methods, circuit board material, and usage environ-ment. The user should closely review these areas when considering use of a UCSP package. Performance through Operating Life Test and Moisture Resistance remains uncompromised as the wafer-fabrication process primarily determines it.Mechanical stress performance is a greater considera-tion for a UCSP package. UCSPs are attached through direct solder contact to the user’s PC board, foregoing the inherent stress relief of a packaged product lead frame. Solder joint contact integrity must be consid-ered. Table 4 shows the testing done to characterize the UCSP reliability performance. In conclusion, the UCSP is capable of performing reliably through envi-ronmental stresses as indicated by the results in the table. Additional usage data and recommendations are detailed in the UCSP application note, which can be found on Maxim’s website at .Table 4.

MAX3057ASA中文资料
General DescriptionThe MAX3050/MAX3057 interface between the CAN protocol controller and the physical wires of the bus lines in a controller area network (CAN). They are pri-marily intended for automotive systems requiring data rates up to 2Mbps and feature ±80V fault protection against short circuits in high-voltage power buses. They provide differential transmit capability to the bus and differential receive capability to the CAN controller. The MAX3050/MAX3057 have four modes of operation:high speed, slope control, standby, and shutdown.High-speed mode allows data rates up to 2Mbps. In slope-control mode, data rates are 40kbps to 500kbps,so the effects of EMI are reduced, and unshielded twisted or parallel cable can be used. In standby mode,the transmitters are shut off and the receivers are put into low-current mode. In shutdown mode, the transmit-ter and receiver are switched off.The MAX3050 has an AutoShutdown™ function that puts the device into a 15µA shutdown mode when the bus or CAN controller is inactive for 4ms or longer.The MAX3050/MAX3057 are available in an 8-pin SO package and are specified for operation from -40°C to +125°C.ApplicationsAutomotive Systems HVAC Controls Telecom 72V systemsFeatureso ±80V Fault Protection for 42V Systems o Four Operating ModesHigh-Speed Operation Up to 2Mbps Slope-Control Mode to Reduce EMI (40kbps to 500kbps)Standby ModeLow-Current Shutdown Mode o AutoShutdown when Device Is Inactive (MAX3050)o Automatic Wake-Up from Shutdown (MAX3050)o Thermal Shutdown o Current Limitingo Fully Compatible with the ISO 11898 Standard*MAX3050/MAX3057±80V Fault-Protected, 2Mbps, Low SupplyCurrent CAN Transceivers________________________________________________________________Maxim Integrated Products 1Ordering InformationTypical Operating Circuit19-2670; Rev 0; 10/02For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at1-888-629-4642, or visit Maxim’s website at .Pin ConfigurationAutoShutdown is a trademark of Maxim Integrated Products, Inc.*Pending completion of testing.M A X 3050/M A X 3057±80V Fault-Protected, 2Mbps, Low Supply Current CAN Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSDC ELECTRICAL CHARACTERISTICS(V CC = +5V ±10%, R L = 60Ω, RS = GND, T A = T MIN to T MAX .

They are primarily intended for automotive appli-cations requiring data rates up to 2Mbps and feature ±80V fault protection against shorts in high-voltage sys-tems. This fault protection allows the devices to with-stand up to ±80V with respect to ground with no damage to the device. The built-in fault tolerance allows the device to survive in industrial and automotive environments with no external protection devices. The devices provide differential transmit capability to the bus and differential receive capability to the CAN con-troller (Figure 4).The device has four modes of operation: high speed,slope control, standby, and shutdown. In high-speed mode, slew rates are not limited, making 2Mbps transmis-sion speeds possible. Slew rates are controlled in slope-control mode, minimizing EMI and allowing use of unshielded twisted or parallel cable. In standby mode,receivers are active and transmitters are in high imped-ance. In shutdown mode, transmitters and receivers are turned off.The transceivers are designed to operate from a single +5V supply and draw 56mA of supply current in domi-nant state and 3.6mA in recessive state. In standby mode, supply current is reduced to 125µA. In shutdown mode, supply current is 15µA.CANH and CANL are output short-circuit current limited and are protected against excessive power dissipation by thermal-shutdown circuitry that places the driver outputs into a high-impedance state.Fault ProtectionThe MAX3050/MAX3057 feature ±80V fault protection.This extended voltage range of CANH and CANL bus lines allows use in high-voltage systems and communi-cation with high-voltage buses. If data is transmitting at 2Mbps, the fault protection is reduced to ±70V.TransmitterThe transmitter converts a single-ended input (TXD)from the CAN controller to differential outputs for the bus lines (CANH, CANL). The truth table for the trans-mitter and receiver is given in Table 1.±80V Fault-Protected, 2Mbps, Low Supply Current CAN Transceivers 8_______________________________________________________________________________________Figure 4. Functional DiagramHigh SpeedConnect RS to ground to set the MAX3050/MAX3057 to high-speed mode. When operating in high-speed mode, the MAX3050/MAX3057 can achieve transmis-sion rates of up to 2Mbps. Line drivers are switched on and off as quickly as possible. However, in this mode,no measures are taken to limit the rise and fall slope of the data signal, allowing for potential EMI emissions. If using the MAX3050/MAX3057 in high-speed mode, use shielded twisted-pair cable to avoid EMI problems.Slope ControlConnect a resistor from RS to ground to select slope-control mode (Table 2). In slope-control mode, the gates of the line drivers are charged with a controlled current, proportional to the resistor connected to the RS pin. Transmission speed ranges from 40kbps to 500kbps. Controlling the rise and fall slope reduces EMI and allows the use of an unshielded twisted pair or a parallel pair of wires as bus lines. The transfer func-tion for selecting the resistor value is given by:R RS (k Ω) = 12000/speed (in kbps)See the Slew Rate vs. R RS graph in the Typical Operating Characteristics section.ReceiverThe receiver reads differential input from the bus lines (CANH, CANL) and transfers this data as a single-ended output (RXD) to the CAN controller. It consists of a comparator that senses the difference ∆V = (CANH -CANL) with respect to an internal threshold of 0.7V. If this difference is positive (i.e., ∆V > 0.7V), a logic low ispresent at the RXD pin. If negative (i.e., ∆V < 0.7V), a logic high is present.The receiver always echoes the transmitted data.The CANH and CANL common-mode range is -7V to +12V. RXD is logic high when CANH and CANL are shorted or terminated and undriven. If the differential receiver input voltage (CANH - CANL) is less than or equal to 0.5V, RXD is logic high. If (CANH - CANL) is greater than or equal to 0.9V, RXD is logic low.StandbyIf a logic high level is applied to RS, the MAX3050/MAX3057 enter a low-current standby mode. In this mode, the transmitter is switched off and the receiver is switched to a low-current state. If dominant bits are detected, RXD switches to a low level. The microcon-troller should react to this condition by switching the transceiver back to normal operation (through RS). Due to the reduced power mode, the receiver is slower in standby mode, and the first message may be lost at higher bit rates.Thermal ShutdownIf the junction temperature exceeds +160°C, the device is switched off. The hysteresis is approximately 20°C,disabling thermal shutdown once the temperature reaches +140°C.Shutdown (MAX3057)Drive SHDN low to enter shutdown mode. In shutdown mode, the device is switched off. The outputs are high impedance to ±80V. The MAX3057 features a pullup at SHDN . If shutdown is forced low and then left floating,the device switches back to normal operating mode.MAX3050/MAX3057±80V Fault-Protected, 2Mbps, Low SupplyCurrent CAN TransceiversTable 1. Transmitter and Receiver Truth Tablelogical 0 and the recessive represents the logical 1. During the simultaneous transmission of the dominant and recessive bits, the result-ing bus value is dominant.Table 2. Mode Selection Truth TableM A X 3050/M A X 3057AutoShutdown (MAX3050)To manage power consumption, AutoShutdown puts the device into shutdown mode after the device has been inactive for a period of time. The value of an external capacitor (C SHDN ) connected to SHDN deter-mines the threshold of inactivity time, after which the AutoShutdown triggers. F loating SHDN allows the MAX3050 to automatically change from active mode to shutdown.Use a 100nF capacitor as C SHDN for a typical thresh-old of 20ms. Change the capacitor value according to the following equation to change the threshold time period.V SHDN is the threshold of SHDN guaranteed to be less than 2V in the Electrical Characteristics table. Drive SHDN high to turn the MAX3050 on and disable AutoShutdown.When the MAX3050 is in shutdown mode, only the wake-up comparator is active, and normal bus commu-nication is ignored. The remote master of the CAN sys-tem wakes up the MAX3050 with a signal greater than 9V on CANH. Internal circuitry in the MAX3050 puts the device in normal operation by driving SHDN high. The MAX3057 does not have the AutoShutdown feature.Driver Output ProtectionThe MAX3050/MAX3057 have several features that pro-tect them from damage. Thermal shutdown switches off the device and puts CANH and CANL into high imped-ance if the junction temperature exceeds +160°C.Thermal protection is needed particularly when a bus line is short circuited. The hysteresis for the thermal shutdown is approximately 20°C.Additionally, a current-limiting circuit protects the trans-mitter output stage against short-circuits to positive and negative battery voltage. Although the power dissipa-tion increases during this fault condition, this featureprevents destruction of the transmitter output stage.±80V Fault-Protected, 2Mbps, Low Supply Current CAN Transceivers 10______________________________________________________________________________________Figure 5. FFT Dominant Bus at 2MbpsFigure 6. FFT Recessive Bus at 2MbpsFigure 7. FFT Dominant Bus at 500kbpsApplications InformationReduced EMI and ReflectionsIn slope-control mode, the CANH and CANL outputs are slew-rate limited, minimizing EMI and reducing reflections caused by improperly terminated cables. In general, a transmitter ’s rise time relates directly to the length of an unterminated stub, which can be driven with only minor waveform reflections. The following equation expresses this relationship conservatively:Length = t RISE / (15ns/ft)where t RISE is the transmitter ’s rise time.The MAX3050 and MAX3057 require no special layout considerations beyond common practices.

MAX32620 EV Kit Contents in BoxEvaluates: MAX32620, MAX32621 MAX32620 Evaluation KitGetting Started1) While observing safe ESD practices, carefully re-move the EV kit board out of its packaging. Quicklyinspect the board to make sure that no damageoccurred during shipment. Jumpers/shunts were pre-installed prior to testing and packaging. By default,they select the USB interface as the source of power for the EV kit board. See Table 1 and Figure 4 for the default jumper settings and descriptions.2) The MAX32620/21 was preprogrammed with a demoprogram. To power up the board and run the demo,simply connect the Micro-USB cable to the Micro-USB jack found at the top left of the EV kit PCB. The jack is labeled CN2. The other end of the Micro-USB cable can be connected either to a computer or to a USB wall charger in order to get +5V power. No data is sent over USB in this demo.3) Once power is applied, the demo will run. The demodisplays text and graphics on the OLED display.4) If the OLED display does not show a graphicsscreen, then verify that the USB port is supplying+5V.5) Do not connect any of the additional USB cables orOlimex JTAG adapter until after the tool chain/drivers are installed.If the demo ran as expected, then the next step is to download and run the installer as described in the Quick Start (separate document). The installer is a small appli-cation that allows users to select which components they would like to download and install including tools, drivers, and documentation. A description of each component and the hard drive size required for each can be seen by clicking on each component.Figure 2.

MAX32620 EV Kit BoardEvaluates: MAX32620, MAX32621 MAX32620 Evaluation KitDetailed Description of HardwareThis section describes each major function or component on the MAX32620 EV kit. This EV kit is general-purpose in nature and provides many user-selectable options, which are described in the following sections. Each jump-er setting is described and its default setting illustrated. Board PowerThe EV kit’s main power-supply input is +5V, made avail-able through Micro-USB type-B connector CN2. This is the default power source.Current MonitoringJumpers JP15, JP16, JP18, and JP19 provide conve-nient current monitoring points for VDD12 (JP15), VRTC (JP18), VDDB (JP19), and VDDA+VDD18 (JP16). PushbuttonsPushbuttons (normally open) SW1, SW2, and SW3 can be used to generate a logic 0 signal on their correspond-ing GPIO port pins. Firmware defines the action taken on switch closure.Pushbutton SW4 provides a global POR reset function for the MAX32620/21 by asserting the RSTN input. Pushbutton SW5 controls the PFN1 input of the PMIC. The function of the PFN1 input is configurable. Refer to the MAX14690 IC data sheet for complete information. USBThe MAX32620/21 provides an integrated USB2.0 full-speed interface (12Mbps). This interface is accessed through the Micro-USB type-B connector, CN2. This interface is also the default power source for the EV kit. USB-UART BridgeThe EV kit board provides a USB-to-UART bridge chip, FTDI FT230X. This bridge eliminates the requirement for a physical RS-232 COM port. Instead, MAX32620/21 UART access is through the Micro-USB type-B connector, CN1. Virtual COM port drivers and guides for installing Windows® drivers are available at . Default parameters are 115,200 baud, 8 bits, no parity, 1 stop bit, no flow control.The USB-to-UART bridge can be connected to UART 0 or UART 1 of the MAX32620/21 with jumpers JP10 (RX), JP12 (TX), JP13 (CTS), and JP14 (RTS).LEDsThe EV kit board has four LEDs with series current- limiting resistors. LEDs DS1 (red), DS2 (green), DS3 (red), and DS4 (green) are connected to MAX32620/21 GPIO pins P3.0, P3.1, P3.2, and P3.3, respectively. LED GPIOs should be configured as open drain due to 3.3V LED source voltages. An LED is illuminated when the appropriate GPIO pin is driven low.Bluetooth Low-Energy (BLE) ControllerThe EV kit board has a low-power Bluetooth control-ler, EM9301. Communication with the MAX32620/21 is through SPI 2B. This particular SPI port was selected due to the additional flow control signals that it features. The EM9301 controller is Bluetooth specification V4.0 compli-ant. Refer to the EM Microelectronic EM9301 data sheet for additional details.ClockingThe MAX32620/21 operate from an internal 96MHz relaxation oscillator. The internal oscillator is adequate to run the core digital logic and peripherals. The accuracy of the internal oscillator is not suitable for accurate RTC timekeeping or USB operation. The external 32.768kHz crystal, Y1, provides the RTC with an accurate time base and is also used to calibrate the internal oscillator for the accuracy required for USB operation.JTAG ConnectorThe ARM standard 20-pin connector pinout is provided by shrouded header J1. Various debugger modules are available for this interface. The Olimex ARM-USB-TINY-H debugger is supplied with the EV kit.Graphic OLED Display ModuleA 128 x 32 pixel graphic OLED display module, NHD-2.23-12832UCB3, is provided on the EV kit board. Communications with the NHD-2.23-12832UCB3 is through SPI 2A.Power Management IC (PMIC)The MAX14690 manages the EV kit power rails. It also manages the selection of EV kit power from either VBUS from CN2 or an (optional) external lithium-ion polymer battery. The MAX14690 can also function as a battery charger. Refer to the MAX14690 IC data sheet for addi-tional information.Prototyping AreaAn area for adding customer-specific circuitry is provided. This matrix is on a 0.1in spacing and is usable for solder or wire-wrap construction. Power and ground rails run through the matrix.Windows is a registered trademark and service mark of Microsoft Corp.Evaluates: MAX32620, MAX32621 MAX32620 Evaluation KitJumper DescriptionsTable 1 details the functions of the configurable jumper headers on the EV kit board.

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。

Typical Application Circuit
The MAX3266 is a transimpedance preamplifier for 1.25Gbps local area network (LAN) fiber optic receivers. The circuit features 200nA input-referred noise, 920MHz bandwidth, and 1mA input overload. The MAX3267 provides a pin-for-pin compatible solution for communications up to 2.5Gbps. It features 500nA input-referred noise, 1.9GHz bandwidth, and 1mA input overload. Both devices operate from a +3.0V to +5.5V single supply and require no compensation capacitor. They also include a space-saving filter connection that provides positive bias for the photodiode through a 1.5kΩ resistor to VCC. These features allow easy assembly into a TO-46 or TO-56 header with a photodiode. The 1.25Gbps MAX3266 has a typical optical dynamic range of -24dBm to 0dBm in a shortwave (850nm) configuration or -27dBm to -3dBm in a longwave (1300nm) configuration. The 2.5Gbps MAX3267 has a typical optical dynamic range of -21dBm to 0dBm in a shortwave configuration or -24dBm to -3dBm in a longwave configuration.
