Type
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.
Bias Reference Resistor 10. This pin should be connected to a 549 Ω
pull-down resistor.
Bias reference Resistor 100. This pin should be connected to a 619 Ω
pull-down resistor.
