Transmitter SectionTX_DisableTX disable is an input pin that is used to shut down the XGSPON transmitter optical output at the same time. 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 – VCC): Transmitter Disabled; Open: Transmitter Disabled. The TX disable signal is high

(LVTTL logic “1”) to turn off the laser output. The laser will turn on when TX_Disable is low (LVTTL logic “0”).

XGSPON TD+/-XGSPON_TD+/- are the differential XGSPON transmitter inputs. They are AC-coupled, differential lines with 100Ω

differential termination inside the module. It allows a differential input swing of 120-850mV, 9.953Gbps data rate.

Receiver SectionXGSPON_SDSD (Signal Detect) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩresistor to voltage

between 2.4V and Vcc+0.3V. When low, this output indicates the received optical power is below the worst-case

receiver sensitivity (as defined by the standard in use). High indicates normal operation. In the low state, the output

will be pulled to < 0.4V.


_______________________________________________________________________________________


XGSPON RD+/-These are the XGSPON differential receiver outputs. They are DC coupled 100Ω differential lines which should be

terminated with 100 Ω (differential) at the user SERDES. The AC coupling is done on the host board. The voltage

swing on these lines will be between 400 and 800 mV differential output when properly terminated.
