open drain driver capable of driving a 10mA LED.
Redundant Link Output Pin. The pin will be asserted (LOW)
if the device is in either the link-fail state or if it senses a
remote fault condition.
Scrambler Enable for TP Port Output. Active high, internal
pull up.
Elastic Store of TP to Fiber Path Disable. Active high,
internal pull down.
Elastic Store of Fiber to TP Path Disable. Active high,
internal pull down.
Secondary Channel Data Out.
Pause Capability Advertisement Enable. Active high, internal
pull up.
Power Supply. (+5V)
Leave unconnected.
PECL output pins for driving the fiber optic module.

Fiber Receive Ground.
PECL input pins for driving the fiber optic module.
Fiber Receiver Power Supply. (+5V)
Enables Full Duplex Auto-negotiation FLP. Active high,
