OPEN

DRAIN

COLLISION INPUT: Differential collision input pair from the

transceiver

TP Driver Outputs. These two outputs provide the TP drivers with

pre-distortion capability

TP Receive Input. A differential receiver tie to the receive

transformer pair of the twisted-pair wire.

The receive pair of the twisted-pair medium is driven with 10

Mbits/s Manchester-encoded data

LINK and Traffic LED Driver: If TP is LINK-pass, this pin outputs low.

This pin will go low for 80ms and then into high impedance state for

50ms to indicate the presence of traffic on the network

No connection

+5V DC power supply for analog CKT. A decoupling capacitor

should be connected between these pins and GND for analog CKT
