    MAX3097E/MAX3098E
    ±15kV ESD-Protected, 32Mbps, 3V/5V,
    Triple RS-422/RS-485 Receivers with Fault Detection
    ______________________________________________________________________________________

    Common-Mode Range
    The MAX3097E/MAX3098E contain circuitry that de-
    tects if the input stage is going outside its useful com-
    mon-mode range. If the received data could be
    unreliable, a fault signal is triggered.
    Detecting Low Input Differential
    Due to cable attenuation on long wire runs, it is possi-
    ble that VID < 200mV, and incorrect data will be
    received. In this condition, a fault will be indicated.
    Delayed Fault Output
    The 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 (10A typ) is shunted to
    ground. Upon activation of any alarm from receiver A,
    B, or Z, the MOSFET is turned off, allowing the current
    source to charge CDELAY. When VDELAY exceeds the
    DELAY threshold, the comparator output, ALARMD,
    goes high. ALARMD is reset when all receiver alarms
    go low, quickly discharging CDELAY to ground.
    Setting Delay Time
    ALARMD’s delay time is set with a single capacitor
    connected from DELAY to GND. The delay comparator
    threshold varies with supply voltage, and the CDELAY
    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:
    tD = 15 + 0.33 x CDELAY (for VCC = 5V)
    and
    tD = 10 + 0.187 x CDELAY (for VCC = 3V)
    where tD is in s and CDELAY is in pF.

    If the duration of an ALARM_ pulse is less than tDLY, no alarm
    output will be present at ALARMD.
