General DescriptionThe MAX2605–MAX2609 evaluation kits (EV kits) simplify evaluation of this family of voltage-controlled oscillators (VCOs). These kits enable testing of the devices’ per-formance and require no additional support circuitry.Both signal outputs use SMA connectors to facilitate connection to RF test equipment.These EV kits are fully assembled and tested. Their oscil-lation frequencies are set to approximately the midrange of the respective VCOs.Featureso Easy Evaluationo Complete, Tunable VCO Test Board with Tank Circuit o Low Phase Noiseo Fully Assembled and TestedEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits19-1673 Rev 0; 9/00Ordering InformationComponent SuppliersFor free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.MAX2606 Component ListMAX2605 Component ListE v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 2_______________________________________________________________________________________Quick StartThe MAX2605–MAX2609 evaluation kits are fully assembled and factory tested. Follow the instructions in the Connections a nd Setup section for proper device evaluation.Test Equipment Required•Low-noise power supplies (these are recommended for oscillator noise measurement). Noise or ripple will frequency-modulate the oscillator and cause spectral spreading. Batteries can be used in place of power supplies, if necessary.– Use a DC power supply capable of supplying +2.7V to +5.5V. Alternatively, use two or three 1.5V batteries.– Use a DC power supply capable of supplying +0.4V to +2.4V, continuously variable, for TUNE.Alternatively, use two 1.5V batteries with a resistive voltage divider or potentiometer.•An RF spectrum analyzer that covers the operating frequency range of the MAX2605–MAX2609• A 50Ωcoaxial cable with SMA connectors •An ammeter (optional)Connections and Setup1)Connect a DC supply (preset to +3V) to the V CC and GND terminals (through an ammeter, if desired) on the EV kit.2)Turn on the DC supply. If used, the ammeter readingMAX2607 Component ListMAX2608 Component ListEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits_______________________________________________________________________________________3approximates the typical operating current specified in the MAX2605–MAX2609 data sheet.3)Connect the VCO output (OUT+ or OUT-) to a spec-trum analyzer with a 50Ωcoaxial cable.4)Apply a positive variable DC voltage between 0.4V and 2.4V to TUNE.5)Check the tuning bandwidth on the spectrum analyz-er by varying the tuning voltage (+0.4V to +2.4V).Layout ConsiderationsThe EV kit PC board can serve as a guide for laying out a board using the MAX2605–MAX2609. Generally, the VCC pin on the PC board should have a decoupling capacitor placed close to the IC. This minimizes noisecoupling from the supply. Also, place the VCO as far away as possible from the noisy section of a larger sys-tem, such as a switching regulator or digital circuits.The VCO ’s performance is strongly dependent on the availability of the external tuning inductor. For best per-formance, use high-Q components and choose their val-ues carefully. To minimize the effects of parasitic ele-ments, which degrade circuit performance, place the tuning inductor and C BYP close to the VCO. For higher-frequency versions, include the parasitic PC board inductance and capacitance when calculating the oscillation frequency. In addition, remove the ground plane around and under the tuning inductor to minimize the effect of parasitic capacitance.Noise on TUNE translates into FM noise on the outputs;therefore, keep the trace between TUNE and the control circuitry as short as possible. If necessary, use an RC filter to further suppress noise, as done on the EV kits.E v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 4_______________________________________________________________________________________Figure 2.

±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 TransceiversThe major difference between tests done using the Human Body Model and IEC1000-4-2 is higher peak current in IEC1000-4-2, because series resistance is lower in the IEC1000-4-2 model. Hence, the ESD with-stand voltage measured to IEC1000-4-2 is generally lower than that measured using the Human Body Model. Figure 7 shows the current waveform for the 8kV IEC1000-4-2 ESD contact-discharge test.The air-gap 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 Model The 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. Of course, all pins require this protec-tion during manufacturing—not just inputs and outputs. Therefore,after PC board assembly,the Machine Model is less relevant to I/O ports.MAX487E/MAX1487E:128 Transceivers on the Bus The 48kΩ, 1/4-unit-load receiver input impedance of the MAX487E and MAX1487E allows up to 128 transceivers on a bus, compared to the 1-unit load (12kΩinput impedance) of standard RS-485 drivers (32 transceivers maximum). Any combination of MAX487E/MAX1487E and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus. The MAX481E, MAX483E, MAX485E, and MAX488E–MAX491E have standard 12kΩreceiver input impedance.MAX483E/MAX487E/MAX488E/MAX489E:Reduced EMI and Reflections The MAX483E and MAX487E–MAX489E are slew-rate limited, minimizing EMI and reducing reflections caused by improperly terminated cables. F igure 16 shows the driver output waveform and its Fourier analy-sis of a 150kHz signal transmitted by a MAX481E, MAX485E, MAX490E, MAX491E, or MAX1487E. High-frequency harmonics with large amplitudes are evident.F igure 17 shows the same information displayed for a MAX483E, MAX487E, MAX488E, or MAX489E transmit-ting under the same conditions. F igure 17’s high-fre-quency harmonics have much lower amplitudes, and the potential for EMI is significantly reduced.Low-Power Shutdown Mode(MAX481E/MAX483E/MAX487E) A low-power shutdown mode is initiated by bringing both RE high and DE low. The devices will not shut down unless both the driver and receiver are disabled. In shutdown, the devices typically draw only 0.5µA of supply current.RE and DE may be driven simultaneously; the parts are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown.F or the MAX481E, MAX483E, and MAX487E, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485E, MAX488E–MAX491E, and MAX1487E can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics).Figure 16.

MAX3098EAESE中文资料
General DescriptionThe MAX3097E/MAX3098E feature three high-speed RS-485/RS-422 receivers with fault-detection circuitry and fault-status outputs. The receivers’ inputs have fault thresholds that detect when the part is not in a valid state.The MAX3097E/MAX3098E indicate when a receiver input is in an open-circuit condition, short-circuit condi-tion, or outside the common-mode range. They also generate a fault indication when the differential input voltage goes below a preset threshold. See Ordering Information or the Electrical Characteristics for thresh-old values.The fault circuitry includes a capacitor-programmable delay to ensure that there are no erroneous fault condi-tions even at slow edge rates. Each receiver is capable of accepting data at rates up to 32Mbps.________________________ApplicationsRS-485/RS-422 Receivers for Motor-Shaft EncodersHigh-Speed, Triple RS-485/RS-422 Receiver with Extended Electrostatic Discharge (ESD)Triple RS-485/RS-422 Receiver with Input Fault IndicationTelecommunications Embedded SystemsFeatureso Detects the Following RS-485 Faults:Open-Circuit Condition Short-Circuit ConditionLow Differential Voltage Signal Common-Mode Range Violationo ESD Protection±15kV—Human Body Model±15kV—IEC 1000-4-2, Air-Gap Discharge Method±8kV—IEC 1000-4-2, Contact Discharge Method o Single +3V to +5.5V Operationo -10V to +13.2V Extended Common-Mode Range o Capacitor-Programmable Delay of Fault Indication Allows Error-Free Operation at Slow Data Rates o Independent and Universal Fault Outputs o 32Mbps Data Rateo 16-Pin QSOP is 40% Smaller than Industry-Standard 26LS31/32 SolutionsMAX3097E/MAX3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection________________________________________________________________Maxim Integrated Products1Pin ConfigurationTypical Application Circuit19-1727; Rev 0; 7/00For free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.Ordering InformationOrdering Information continued at end of data sheet.M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Common-Mode Fault Propagation DelayTest Circuits and WaveformsDetailed DescriptionThe MAX3097E/MAX3098E feature high-speed, triple RS-485/RS-422 receivers with fault-detection circuitry and fault-status outputs. The fault outputs are active push-pull, requiring no pull-up resistors. The fault cir-cuitry includes a capacitor-programmable delayed FAULT_ output to ensure that there are no erroneous fault conditions even at slow edge rates (see Delayed Fault Output ). The receivers operate at data rates up to 32Mbps.The MAX3097E/MAX3098E are designed for motor-shaft encoders with standard A, B, and Z outputs (see Using the M AX3097E/M AX3098E as Shaft Encoder Receivers ). The devices provide an alarm for open-cir-cuit conditions, short-circuit conditions, data nearing the minimum differential threshold conditions, data below the minimum threshold conditions, and receiver inputs outside the input common-mode range. Tables 1and 2 are functional tables for each receiver.M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 8_______________________________________________________________________________________Note 1:ALARMD indicates fault for any receiver.Note 2:Receiver output may oscillate with this differential input condition.Note 3:See Applications Information for conditions leading to input range fault condition.X = Don ’t careNote 1:ALARMD indicates fault for any receiver.Note 2:Receiver output may oscillate with this differential input condition.Note 3:See Applications Information for conditions leading to input range fault condition.X = Don ’t care; for B-grade functionality, replace V ID input values in Table 2 with B-grade parameters from Electrical Characteristics.MAX3097E/MAX3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection_______________________________________________________________________________________9±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against ESD encountered during handling and assembly. The MAX3097E/MAX3098E receiver inputs have extra pro-tection against static electricity found in normal opera-tion. Maxim ’s engineers developed state-of-the-art structures to protect these pins against ±15kV ESD without damage. After an ESD event, the MAX3097E/MAX3098E continue working without latchup.ESD protection can be tested in several ways. The receiver inputs are characterized for protection to the following:•±15kV using the Human Body Model•±8kV using the Contact Discharge method specified in IEC 1000-4-2 (formerly IEC 801-2)•15kV using the Air-Gap Discharge method specified in IEC 1000-4-2 (formerly IEC 801-2)ESD Test ConditionsESD performance depends on a number of conditions.Contact Maxim for a reliability report that documents test setup, methodology, and results.Human Body ModelFigure 5a shows the H uman Body Model, and Figure 5b 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 device through a 1.5k Ωresistor.IEC 1000-4-2Since January 1996, all equipment manufactured and/or sold in the European community has been required to meet the stringent IEC 1000-4-2 specification. The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifically refer to inte-grated circuits. The MAX3097E/MAX3098E help you design equipment that meets Level 4 (the highest level)of IEC 1000-4-2, without additional ESD-protection com-ponents.The main difference between tests done using the H uman 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 ESD test model (Figure 6a), the ESD-withstand voltage measured to this standard is gen-erally lower than that measured using the Human Body Model. Figure 6b shows the current waveform for the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.The Air-Gap test involves approaching the device with a charge probe. The Contact Discharge method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD testing uses a 200pF stor-age capacitor and zero-discharge resistance. It mimics the stress caused by handling during manufacturing and assembly. All pins (not just RS-485 inputs) require this protection during manufacturing. Therefore, the Machine Model is less relevant to the I/O ports than are the Human Body Model and IEC 1000-4-2.Figure 5a. Human Body ESD Test ModelFigure 5b. Human Body Model Current Waveform___________Applications InformationUsing the MAX3097E/MAX3098E as ShaftEncoder ReceiversThe MAX3097E/MAX3098E are triple RS-485 receivers designed for shaft encoder receiver applications. A shaft encoder is an electromechanical transducer that converts mechanical rotary motion into three RS-485differential signals. Two signals, A (A and A) and B (B and B) provide incremental pulses as the shaft turns,while the index signal, Z (Z and Z) occurs only once per revolution to allow synchronization of the shaft to a known position. Digital signal processing (DSP) tech-niques are used to count the pulses and provide feed-back of both shaft position and shaft velocity for a stable positioning system.Shaft encoders typically transmit RS-485 signals over twisted-pair cables since the signal often has to travel across a noisy electrical environment (Figure 7).Detecting FaultsSignal integrity from the shaft encoder to the DSP is essential for reliable system operation. Degraded sig-nals could cause problems ranging from simple mis-counts to loss of position. In an industrial environment,many problems can occur within the three twisted pairs. The MAX3097E/MAX3098E can detect various types of common faults, including a low-input-level sig-nal, open-circuit wires, short-circuit wires, and an input signal outside the common-mode input voltage range of the receiver.Detecting Short CircuitsIn Figure 8, if wires A and A are shorted together, then A and A will be at the same potential, so the difference in the voltage between the two will be approximately 0. This causes fault A to trigger since the difference between A -A is less than the differential fault threshold.Detecting Open-Circuit ConditionsDetecting an open-circuit condition is similar to detect-ing a short-circuit condition and relies on the terminat-ing resistor being across A and A . For example, if the wire drops out of the A terminal, A pulls A through the terminating resistor to look like the same signal. In this condition, V ID is approximately 0 and a fault occurs.M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 10______________________________________________________________________________________Figure 7.

If the received data could be unreliable, a fault signal is triggered.Detecting Low Input DifferentialDue to cable attenuation on long wire runs, it is possi-ble that V ID < 200mV, and incorrect data will be received. In this condition, a fault will be indicated.Delayed Fault OutputThe delayed fault output provides a programmable blanking delay to allow transient faults to occur without triggering an alarm. Such faults may occur with slow signals triggering the receiver alarm through the zero crossover region.Figure 9 shows the delayed alarm output.ALARMD performs a logic OR of ALARMA, ALARMB,and ALARMZ (Figure 10). A NOR gate drives an N-channel MOSFET so that in normal operation with no faults, the current source (10µA typ) is shunted toground. Upon activation of any alarm from receiver A,B, or Z, the MOSFET is turned off, allowing the current source to charge C DELAY . When V DELAY exceeds the DELAY threshold, the comparator output, ALARMD,goes high. ALARMD is reset when all receiver alarms go low, quickly discharging C DELAY to ground.Setting Delay TimeALARMD ’s delay time is set with a single capacitor connected from DELAY to GND. The delay comparator threshold varies with supply voltage, and the C DELAY value can be determined for a given time delay period from the Capacitance vs. ALARMD Output Delay graph in the Typical Operating Characteristics or using the following equations:t D = 15 + 0.33 x C DELAY (for V CC = 5V)andt D = 10 + 0.187 x C DELAY (for V CC = 3V)where t D is in µs and C DELAY is in pF.M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 12______________________________________________________________________________________Chip InformationTRANSISTOR COUNT: 675PROCESS: CMOSMAX3097E/MAX3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection______________________________________________________________________________________13Package InformationM A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 14______________________________________________________________________________________Package Information (continued)MAX3097E/MAX3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection______________________________________________________________________________________15Package Information (continued)M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection M axim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a M axim product.

These µP supervisory circuits assert reset to prevent code execution errors during power-up, power-down, brownout conditions, or a watchdog timeout.–R —E —S —E —T –is guaranteed to be a logic low for 0V < V CC <V RST , provided that VBATT is greater than 1V. Withouta backup battery,–R —E —S —E —T –is guaranteed valid for V CC > 1V. Once V CC exceeds the reset threshold, aninternal timer keeps –R —E —S —E —T –low for the reset timeoutperiod; after this interval,–R —E —S —E —T –goes high (Figure 2).If a brownout condition occurs (V CC dips below thereset threshold),–R —E —S —E —T – goes low. Each time –R —E —S —E —T –is asserted, it stays low for the reset timeout period.Any time V CC goes below the reset threshold, the internal timer restarts.The watchdog timer can also initiate a reset. See the Watchdog Input section.The MAX804_/MAX805_ active-high RESET output is open drain, and the inverse of the MAX690_/MAX704_/MAX802_/MAX806_–R —E —S —E —T –output.Reset ThresholdThe MAX690T/MAX704T/MAX805T are intended for 3.3V systems with a ±5% power-supply tolerance and a 10% system tolerance. Except for watchdog faults,reset will not assert as long as the power supply remains above 3.15V (3.3V - 5%). Reset is guaranteed to assert before the power supply falls below 3.0V.The MAX690S/MAX704S/MAX805S are designed for 3.3V ±10% power supplies. Except for watchdog faults, they are guaranteed not to assert reset as long as the supply remains above 3.0V (3.3V - 10%). Reset is guaranteed to assert before the power supply falls below 2.85V (V CC - 14%).The MAX690R/MAX704R/MAX805R are optimized for monitoring 3.0V ±10% power supplies. Reset will not occur until V CC falls below 2.7V (3.0V - 10%), but is guaranteed to occur before the supply falls below 2.59V (3.0V - 14%).The MAX802R/S/T, MAX804R/S/T, and MAX806R/S/T are respectively similar to the MAX690R/S/T,MAX805R/S/T, and MAX704R/S/T, but with tightened reset and power-fail threshold tolerances.3.0V/3.3V Microprocessor Supervisory Circuits 6_____________________________________________________________________________________________________________________________________________________Pin Description1V OUT Supply Output for CMOS RAM. When V CC is above the reset threshold, V OUT isconnected to V CC through a P-channel MOSFET switch. When V CC falls below V SW and VBATT, VBATT connects to V OUT . Connect to V CC if no battery is used.2V CC Main Supply Input 3GND Ground4PFI Power-Fail Input. When PFI is less than V PFT or when V CC falls below V SW , –P —F —O –goeslow; otherwise, –P —F —O –remains high. Connect to ground if unused.7–R —E —S —E —T –Active-Low Reset Output. Pulses low for 200ms when triggered, and stays low wheneverV CC is below the reset threshold or when –M —R –is a logic low. It remains low for 200ms after either V CC rises above the reset threshold, the watchdog triggers a reset, or –M —R –goes from low to high.—–M —R–Manual Reset Input. A logic low on –M —R –asserts reset. Reset remains asserted as long as –M —R –is low and for 200ms after –M —R –returns high. This active-low input has an internal 70µA pull-up current. It can be driven from a TTL or CMOS logic line, or shorted to ground with a switch. Leave open if unused.6WDIWatchdog Input. If WDI remains high or low for 1.6sec, the internal watchdog timer runs out and reset is triggered. The internal watchdog timer clears while reset is asserted or when WDI sees a rising or falling edge. The watchdog function cannot be disabled.5–P —F —O –Power-Fail Output. When PFI is less than V PFT , or V CC falls below V SW , –P —F —O –goes low;otherwise, –P —F —O –remains high. Leave open if unused.8VBATTBackup-Battery Input. When V CC falls below V SW and VBATT, V OUT switches from V CC to VBATT. When V CC rises above the reset threshold, V OUT reconnects to V CC . VBATT may exceed V CC . Connect to V CC if no battery is used.—RESET Active-High, Open-Drain Reset Output is the inverse of –R —E —S —E —T –.NAMEFUNCTIONMAX690MAX80212PIN34——6587MAX804MAX805123476—58—MAX704MAX806Watchdog Input(MAX690_/802_/804_/805_)The watchdog circuit monitors the µP’s activity. If the µP does not toggle the watchdog input (WDI) within 1.6sec,a reset pulse is triggered. The internal 1.6sec timer is cleared by either a reset pulse or by a transition (low-to-high or high-to-low) at WDI. If WDI is tied high or low, a –R —E —S —E —T –pulse is triggered every 1.8sec (t WD plus t RS ).As long as reset is asserted, the timer remains cleared and does not count. As soon as reset is deasserted,the timer starts counting. Unlike the 5V MAX690 family,the watchdog function cannot be disabled.Power-Fail ComparatorThe PFI input is compared to an internal reference. IfPFI is less than V PFT ,–P —F —O –goes low. The power-fail comparator is intended for use as an undervoltage detector to signal a failing power supply. However, the comparator does not need to be dedicated to this function because it is completely separate from the rest of the circuitry.The power-fail comparator turns off and –P —F —O –goes low when V CC falls below V SW on power-down. The power-fail comparator turns on as V CC crosses V SW on power-up. If the comparator is not used, connect PFI toground and leave –P —F —O – unconnected.–P —F —O –may beconnected to –M —R –on the MAX704_/MAX806_ so that a low voltage on PFI will generate a reset (Figure 5b).MAX690T/S/R, 704T/S/R, 802T/S/R, 804–806T/S/R3.0V/3.3V Microprocessor Supervisory Circuits_______________________________________________________________________________________7Figure 1.Block Diagram Figure 2.Timing DiagramM A X 690T /S /R , 704T /S /R , 802T /S /R , 804–806T /S /RBackup-Battery SwitchoverIn the event of a brownout or power failure, it may be necessary to preserve the contents of RAM. With a backup battery installed at VBATT, the devices auto-matically switch RAM to backup power when V CC falls.This family of µP supervisors (designed for 3.3V and 3V systems) doesn’t always connect VBATT to V OUT when VBATT is greater than V CC . VBATT connects to V OUT (through a 140Ωswitch) when V CC is below V SW and VBATT is greater than V CC , or when V CC falls below 1.75V (typ) regardless of the VBATT voltage. This is done to allow the backup battery (e.g., a 3.6V lithium cell) to have a higher voltage than V CC .Switchover at V SW (2.40V) ensures that battery-backup mode is entered before V OUT gets too close to the 2.0V minimum required to reliably retain data in CMOS RAM.Switchover at higher V CC voltages would decrease backup-battery life. When V CC recovers, switchover is deferred until V CC rises above the reset threshold (V RST ) to ensure a stable supply. V OUT is connected to V CC through a 3ΩPMOS power switch.Manual Reset A logic low on –M —R –asserts reset. Reset remains assertedwhile –M —R –is low, and for t WP (200ms) after –M —R –returns high. This input has an internal 70µA pull-up current, soit can be left open if it is not used.–M —R –can be driven with TTL or CMOS logic levels, or with open-drain/collector outputs. Connect a normally open momentary switchfrom –M —R –to GND to create a manual-reset function;external debounce circuitry is not required.__________Applications InformationThese µP supervisory circuits are not short-circuit protected. Shorting V OUT to ground—excluding power-up transients such as charging a decoupling capacitor—destroys the device. Decouple both V CC and VBATT pins to ground by placing 0.1µF capacitors as close to the device as possible.Using a SuperCapas a Backup Power SourceSuperCaps™ are capacitors with extremely high capacitance values (e.g., order of 0.47F) for their size.Figure 3 shows two ways to use a SuperCap as a backup power source. The SuperCap may be connected through a diode to the 3V input (Figure 3a)or, if a 5V supply is also available, the SuperCap may be charged up to the 5V supply (Figure 3b) allowing a longer backup period. Since VBATT can exceed V CC while V CC is above the reset threshold, there are no special precautions when using these µP supervisors with a SuperCap.Operation without a BackupPower SourceThese µP supervisors were designed for battery-backed applications. If a backup battery is not used,connect both VBATT and V OUT to V CC , or use a different µP supervisor such as the MAX706T/S/R or MAX708T/S/R.Replacing the Backup BatteryThe backup power source can be removed while V CC remains valid, if VBATT is decoupled with a 0.1µF capacitor to ground, without danger of triggeringRESET/–R —E —S —E —T –.As long as V CC stays above V SW ,battery-backup mode cannot be entered.Adding Hysteresisto the Power-Fail ComparatorThe power-fail comparator has a typical input hysteresis of 10mV. This is sufficient for most applica-tions where a power-supply line is being monitored through an external voltage divider (see the section Monitoring an Additional Power Supply ).If additional noise margin is desired, connect a resistorbetween –P —F —O –and PFI as shown in Figure 4a. Select the ratio of R1 and R2 such that PFI sees 1.237V (V PFT )when V IN falls to its trip point (V TRIP ). R3 adds the hysteresis and will typically be more than 10 times the value of R1 or R2. The hysteresis window extends both above (V H ) and below (V L ) the original trip point (V TRIP ).3.0V/3.3V Microprocessor Supervisory Circuits 8_______________________________________________________________________________________™ SuperCap is a trademark of Baknor Industries.Connecting an ordinary signal diode in series with R3,as shown in Figure 4b, causes the lower trip point (V L )to coincide with the trip point without hysteresis (V TRIP ),so the entire hysteresis window occurs above V TRIP .This method provides additional noise margin without compromising the accuracy of the power-fail threshold when the monitored voltage is falling. It is useful for accurately detecting when a voltage falls past a threshold.The current through R1 and R2 should be at least 1µA to ensure that the 25nA (max over extended temperature range) PFI input current does not shift the trip point. R3should be larger than 10k Ωso it does not load down the –P —F —O –pin. Capacitor C1 adds additional noise rejection.Monitoring an Additional Power Supply These µP supervisors can monitor either positive or negative supplies using a resistor voltage divider toPFI. –P —F —O –can be used to generate an interrupt to theµP (Figure 5). Connecting –P —F —O – to –M —R –on the MAX704and MAX806 causes reset to assert when the monitored supply goes out of tolerance. Reset remainsasserted as long as –P —F —O –holds –M —R –low, and for 200msafter –P —F —O –goes high.Interfacing to µPswith Bidirectional Reset PinsµPs with bidirectional reset pins, such as the Motorola 68HC11 series, can contend with the MAX690_/MAX704_/MAX802_/MAX806_–R —E —S —E —T –output. If, forexample, the –R —E —S —E —T –output is driven high and the µP wants to pull it low, indeterminate logic levels may result. To correct this, connect a 4.7k Ωresistorbetween the –R —E —S —E —T –output and the µP reset I/O, as inFigure 6. Buffer the –R —E —S —E —T –output to other system components.Negative-Going V CC TransientsWhile issuing resets to the µP during power-up, power-down, and brownout conditions, these supervisors are relatively immune to short-duration negative-going V CC transients (glitches). It is usually undesirable to reset the µP when V CC experiences only small glitches.Figure 7 shows maximum transient duration vs. reset-comparator overdrive, for which reset pulses are not generated. The graph was produced using negative-going V CC pulses, starting at 3.3V and ending below the reset threshold by the magnitude indicated (reset comparator overdrive). The graph shows the maximum pulse width a negative-going V CC transient may typically have without causing a reset pulse to be issued. As the amplitude of the transient increases (i.e., goes farther below the reset threshold), the maximum allowable pulse width decreases. Typically,a V CC transient that goes 100mV below the reset threshold and lasts for 40µs or less will not cause a reset pulse to be issued.A 100nF bypass capacitor mounted close to the V CC pin provides additional transient immunity.MAX690T/S/R, 704T/S/R, 802T/S/R, 804–806T/S/R3.0V/3.3V Microprocessor Supervisory Circuits_______________________________________________________________________________________9Figure 3.

±15kV ESD-Protected, 10Mbps, 3V/5V, Quad RS-422/RS-485 Receivers
________________General Description
The MAX3095/MAX3096 are rugged, low-power, quad, RS-422/RS-485 receivers with electrostatic discharge (ESD) protection for use in harsh environments. All receiver inputs are protected to ±15kV using IEC 10004-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. The MAX3095 operates from a +5V supply, while the MAX3096 operates from a +3.3V supply. Receiver propagation delays are guaranteed to within ±8ns of a predetermined value, thereby ensuring device-to-device matching across production lots. Complementary enable inputs can be used to place the devices in a 1nA low-power shutdown mode in which the receiver outputs are high impedance. When active, these receivers have a fail-safe feature that guarantees a logic-high output if the input is open circuit. They also feature a quarter-unit-load input impedance that allows 128 receivers on a bus. The MAX3095/MAX3096 are pin-compatible, low-power upgrades to the industry-standard ’26LS32. They are available in a space-saving QSOP package.

General DescriptionThe MAX3097E/MAX3098E feature three high-speed RS-485/RS-422 receivers with fault-detection circuitry and fault-status outputs. The receivers’ inputs have fault thresholds that detect when the part is not in a valid state.The MAX3097E/MAX3098E indicate when a receiver input is in an open-circuit condition, short-circuit condi-tion, or outside the common-mode range. They also generate a fault indication when the differential input voltage goes below a preset threshold. See Ordering Information or the Electrical Characteristics for thresh-old values.The fault circuitry includes a capacitor-programmable delay to ensure that there are no erroneous fault condi-tions even at slow edge rates. Each receiver is capable of accepting data at rates up to 32Mbps.________________________ApplicationsRS-485/RS-422 Receivers for Motor-Shaft EncodersHigh-Speed, Triple RS-485/RS-422 Receiver with Extended Electrostatic Discharge (ESD)Triple RS-485/RS-422 Receiver with Input Fault IndicationTelecommunications Embedded SystemsFeatureso Detects the Following RS-485 Faults:Open-Circuit Condition Short-Circuit ConditionLow Differential Voltage Signal Common-Mode Range Violationo ESD Protection±15kV—Human Body Model±15kV—IEC 1000-4-2, Air-Gap Discharge Method±8kV—IEC 1000-4-2, Contact Discharge Method o Single +3V to +5.5V Operationo -10V to +13.2V Extended Common-Mode Range o Capacitor-Programmable Delay of Fault Indication Allows Error-Free Operation at Slow Data Rates o Independent and Universal Fault Outputs o 32Mbps Data Rateo 16-Pin QSOP is 40% Smaller than Industry-Standard 26LS31/32 SolutionsMAX3097E/MAX3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection________________________________________________________________Maxim Integrated Products1Pin ConfigurationTypical Application Circuit19-1727; Rev 0; 7/00For free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.Ordering InformationOrdering Information continued at end of data sheet.M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Common-Mode Fault Propagation DelayTest Circuits and WaveformsDetailed DescriptionThe MAX3097E/MAX3098E feature high-speed, triple RS-485/RS-422 receivers with fault-detection circuitry and fault-status outputs. The fault outputs are active push-pull, requiring no pull-up resistors. The fault cir-cuitry includes a capacitor-programmable delayed FAULT_ output to ensure that there are no erroneous fault conditions even at slow edge rates (see Delayed Fault Output ). The receivers operate at data rates up to 32Mbps.The MAX3097E/MAX3098E are designed for motor-shaft encoders with standard A, B, and Z outputs (see Using the M AX3097E/M AX3098E as Shaft Encoder Receivers ). The devices provide an alarm for open-cir-cuit conditions, short-circuit conditions, data nearing the minimum differential threshold conditions, data below the minimum threshold conditions, and receiver inputs outside the input common-mode range.

The MAX3097E/MAX3098E receiver inputs have extra pro-tection against static electricity found in normal opera-tion. Maxim ’s engineers developed state-of-the-art structures to protect these pins against ±15kV ESD without damage. After an ESD event, the MAX3097E/MAX3098E continue working without latchup.ESD protection can be tested in several ways. The receiver inputs are characterized for protection to the following:•±15kV using the Human Body Model•±8kV using the Contact Discharge method specified in IEC 1000-4-2 (formerly IEC 801-2)•15kV using the Air-Gap Discharge method specified in IEC 1000-4-2 (formerly IEC 801-2)ESD Test ConditionsESD performance depends on a number of conditions.Contact Maxim for a reliability report that documents test setup, methodology, and results.Human Body ModelFigure 5a shows the H uman Body Model, and Figure 5b 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 device through a 1.5k Ωresistor.IEC 1000-4-2Since January 1996, all equipment manufactured and/or sold in the European community has been required to meet the stringent IEC 1000-4-2 specification. The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifically refer to inte-grated circuits. The MAX3097E/MAX3098E help you design equipment that meets Level 4 (the highest level)of IEC 1000-4-2, without additional ESD-protection com-ponents.The main difference between tests done using the H uman 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 ESD test model (Figure 6a), the ESD-withstand voltage measured to this standard is gen-erally lower than that measured using the Human Body Model. Figure 6b shows the current waveform for the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.The Air-Gap test involves approaching the device with a charge probe. The Contact Discharge method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD testing uses a 200pF stor-age capacitor and zero-discharge resistance. It mimics the stress caused by handling during manufacturing and assembly. All pins (not just RS-485 inputs) require this protection during manufacturing. Therefore, the Machine Model is less relevant to the I/O ports than are the Human Body Model and IEC 1000-4-2.Figure 5a. Human Body ESD Test ModelFigure 5b. Human Body Model Current Waveform___________Applications InformationUsing the MAX3097E/MAX3098E as ShaftEncoder ReceiversThe MAX3097E/MAX3098E are triple RS-485 receivers designed for shaft encoder receiver applications. A shaft encoder is an electromechanical transducer that converts mechanical rotary motion into three RS-485differential signals. Two signals, A (A and A) and B (B and B) provide incremental pulses as the shaft turns,while the index signal, Z (Z and Z) occurs only once per revolution to allow synchronization of the shaft to a known position. Digital signal processing (DSP) tech-niques are used to count the pulses and provide feed-back of both shaft position and shaft velocity for a stable positioning system.Shaft encoders typically transmit RS-485 signals over twisted-pair cables since the signal often has to travel across a noisy electrical environment (Figure 7).Detecting FaultsSignal integrity from the shaft encoder to the DSP is essential for reliable system operation. Degraded sig-nals could cause problems ranging from simple mis-counts to loss of position. In an industrial environment,many problems can occur within the three twisted pairs. The MAX3097E/MAX3098E can detect various types of common faults, including a low-input-level sig-nal, open-circuit wires, short-circuit wires, and an input signal outside the common-mode input voltage range of the receiver.Detecting Short CircuitsIn Figure 8, if wires A and A are shorted together, then A and A will be at the same potential, so the difference in the voltage between the two will be approximately 0. This causes fault A to trigger since the difference between A -A is less than the differential fault threshold.Detecting Open-Circuit ConditionsDetecting an open-circuit condition is similar to detect-ing a short-circuit condition and relies on the terminat-ing resistor being across A and A . For example, if the wire drops out of the A terminal, A pulls A through the terminating resistor to look like the same signal. In this condition, V ID is approximately 0 and a fault occurs.M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 10______________________________________________________________________________________Figure 7.

If the received data could be unreliable, a fault signal is triggered.Detecting Low Input DifferentialDue to cable attenuation on long wire runs, it is possi-ble that V ID < 200mV, and incorrect data will be received. In this condition, a fault will be indicated.Delayed Fault OutputThe delayed fault output provides a programmable blanking delay to allow transient faults to occur without triggering an alarm. Such faults may occur with slow signals triggering the receiver alarm through the zero crossover region.Figure 9 shows the delayed alarm output.ALARMD performs a logic OR of ALARMA, ALARMB,and ALARMZ (Figure 10). A NOR gate drives an N-channel MOSFET so that in normal operation with no faults, the current source (10µA typ) is shunted toground. Upon activation of any alarm from receiver A,B, or Z, the MOSFET is turned off, allowing the current source to charge C DELAY . When V DELAY exceeds the DELAY threshold, the comparator output, ALARMD,goes high. ALARMD is reset when all receiver alarms go low, quickly discharging C DELAY to ground.Setting Delay TimeALARMD ’s delay time is set with a single capacitor connected from DELAY to GND. The delay comparator threshold varies with supply voltage, and the C DELAY value can be determined for a given time delay period from the Capacitance vs. ALARMD Output Delay graph in the Typical Operating Characteristics or using the following equations:t D = 15 + 0.33 x C DELAY (for V CC = 5V)andt D = 10 + 0.187 x C DELAY (for V CC = 3V)where t D is in µs and C DELAY is in pF.M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 12______________________________________________________________________________________Chip InformationTRANSISTOR COUNT: 675PROCESS: CMOSMAX3097E/MAX3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection______________________________________________________________________________________13Package InformationM A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection 14______________________________________________________________________________________Package Information (continued)MAX3097E/MAX3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection______________________________________________________________________________________15Package Information (continued)M A X 3097E /M A X 3098E±15kV ESD-Protected, 32Mbps, 3V/5V ,T riple RS-422/RS-485Receivers with Fault Detection M axim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a M axim product.

The MAX308/MAX309 switches operate with ±5V to ±20V bipolar supplies or with a +5V to +30V single supply. Connect V- to GND when operating with a single supply. Both device types can also operate with unbalanced supplies, such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)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 may cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (Figure 1).Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, but does not affect the devices’ low switch resistance and low leakage charac-teristics. Device operation is unchanged, and the differ-ence between V+ and V- should not exceed +44V.M A X 308/M A X 309Precision, 8-Channel/Dual 4-Channel,High-Performance, CMOS Analog Multiplexers 6_____________________________________________________________________________________________________________________________________________________Pin DescriptionFigure 1.
