Receive Differential Pair, Ports 0-7.
These pins receive the
serial bit-stream on 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 interface directly with an isolation transformer.

Signal Description
C20
MDIO
I/O
Management Data Input/Output.
The MDIO signal is a bi-directional data
pin for the Management Data Interface. When this signal is not used, a pull-
up resistor is required.
B19
MDC
I
Management Data Clock.
The MDC signal functions as a clock reference
for the MDIO signal. MDC can operate at a maximum frequency of 3 MHz.
When this signal is not used, a pull-up resistor is required.
