When SD/FXDISn is used as a Signal Detect
input, not as the FX disable input.
VTRIP = (VDD -1.3V) ± 10%.
When SD/FXDISn is used as a Signal Detect
input, not as the FX disable input.
VTRIP = (VDD - 1.3V) ± 10%
When interfacing to 5 V fiber transceivers.
When interfacing to 3.3 V fiber transceivers,
SD_THR is tied to GND.
