Fiber Interface Signal Detect Input.
Fiber Interface Enable.
When this pin in not tied to GND, the fiber interface is enabled and this pin
becomes a Signal Detect ECL input. The trip point for this ECL input is
determined by the voltage applied to the SD_THR pin. When this pin is tied
to GND, the fiber interface is disabled (i.e. TP Interface is enabled).

SD_THR
---
Fiber Interface Signal Detect Threshold Reference.
to this pin sets the reference level for the fiber interface SD input pin so that
the device can directly connect SD pin to both 3.3V and 5V fiber optic
tansceivers. Typically, this pin is either tied to GND (for 3.3V) or to an
external voltage divider (for 5V).
The voltage applied

Transmit Current Set.
An external resistor connected between this pin and GND will set the level
for the transmit outputs.
