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.
Reference Bias Resistor (100 Mbps). This pin should be connected to a pull-down
resistor.
Reference Bias Resistor (10 Mbps). This pin should be connected to a pull-down
resistor.
