Table 2. Pin Description
Notes:
1. TX_DISABLE is an input that is used to shut down the transmitter optical output. It is pulled down with 6.8 k: internal to the transceiver.
2. The signals SDA and SCL designate the two wire serial interface pins. They must be pulled up with a 4.7 k – 10 k: resistor on the host board.
3. Signal Detect is a normally high LVTTL output. When high it indicates the received optical power is adequate for normal operation. When
4. RD-/+ designate the differential receiver outputs. They are ac coupled 100 : differential lines which should be terminated with 100 : differ-
5. V
6. TD-/+ designate the differential transmitter inputs. They are ac coupled differential lines with 100 : differential termination inside the mod-
7. Transmitter and Receiver Ground are common internally on the transceiver PCB. They are electrically connected to signal ground within the
8. TX_FAULT is an open collector/drain output, which must be pulled up with a 4.7k – 10k: resistor on the host board. When high, this output
