AC Coupled. 19 TD- Transmitter Inverted DATA in. AC Coupled. 20 V Transmitter Ground (Common with Receiver Ground) 1 EET Notes: 1. Circuit ground is internally isolated from chassis ground. 2. T is an open collector/drain output, which should be pulled up with a 4.7k 10k Ohms resistor on FAULT the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates a transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the output is pulled to <0.8V. 3. Laser output disabled on T >2.0V or open, enabled on T <0.8V. DIS DIS 4. Should be pulled up with 4.7k 10kohms on host board to a voltage between 2.0V and 3.6V. MOD ABS pulls line low to indicate module is plugged in. c 5. Rate select can also be set through the 2-wire bus in accordance with SFF-8472 v. 12.1 . Rx Rate Select is set at Bit 3, Byte 110, Address A2h. Tx Rate Select is set at Bit 3, Byte 118, Address A2h. Note: writing a 1 selects maximum bandwidth operation. Rate select is the logic OR of the input state of Rate Select Pin and 2-wire bus. 6. LOS is open collector output. Should be pulled up with 4.7k 10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation logic 1 indicates loss of signal.
