    Descriptions

    This transceiver is a single channel optical transceiver module designed to transmit and receive optical serial digital signals as defined in SMPTE 297-2006. It is specifically designed for robust performance in the presence of SDI pathological patterns for SMPTE 259M, SMPTE 344M,SMPTE 292M and SMPTE 424M serial rates.

    Note:

    1. TX-Fault is an open collector/drain output, which should be pulled up with a 4.7K–10KΩ resistor on the host board. Pull up voltage between 2.0V and VCC+0.3V. When high, output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
    2. TX-disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7–10 KΩ resistor. Its states are:

    Low (0 – 0.8V): Transmitter on

    (>0.8, < 2.0V): Undefined

    High (2.0 – 3.465V): Transmitter Disabled

    Open: Transmitter Disabled

    1. These pins should be pulled up with a 4.7K – 10KΩ resistor on the host board. The pull-up voltage shall be VCCT or VCCR. Mod-Def is grounded by the module to indicate that the module is present .
    2. LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates the received optical power is below the worst-case receiver sensitivity(as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
    3. RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board.
    4. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the SFP connector pin. Maximum supply current is 300mA. Recommended host board power supply filtering is shown below. Inductors with DC resistance of less than 1Ω should be used in order to maintain the required voltage at the SFP input pin with3.3V supply voltage. When the recommended supply filtering network is used, hotplugging of the SFP transceiver module will result in an inrush current of no more than 30 mA greater than the steady state value.
    5. TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board.
