Notes
1. Refer to Figure 7.
2. Tx Fault is pulled up to VccT w ith a 4.7k-10k resistor on the host board.
When high, output indicates a laser f ault of some kind. Low indicates normal operation.
3. Refer to section 7-4 about Tx Fault and Tx Shutdow n behavior.
4. Sink Current : 1mA
5. Tx Disable input is internally terminated to VccT via 4.7 k resistor. If pin3 is left open, Tx is disable.
