Description
AUI Data Out:
Differential output pair drives 10 Mb/s
Manchester-encoded data to the AUI transmit pair.
AUI Data In:
Differential input pair receives 10 Mb/s Manchester-encoded
data from the AUI receive pair.
AUI Collision In:
Differential input pair connects to the AUI collision pair.
A collision is indicated by the presence of a 10 MHz +/-15% signal with
duty cycle no worse than 60/40.
