Description

Transmit Differential Pair. The transmit differential pair sends serial bit streams to

the unshielded twisted pair (UTP) cable. The differential pair is a two-level signal in

10BASE-T (Manchester) mode and a three-level signal in 100BASE-TX mode (MLT-

3). These signals directly interface with the isolation transformer.

Receive Differential Pair. The receive differential pair receive the serial bit stream

from an unshielded twisted pair (UTP) cable. The differential pair is a two-level signal

in 10BASE-T mode (Manchester) or a three-level signal in 100BASE-TX mode (MLT-

3). These signals directly interface with an isolation transformer.
