Pin Description
Connect this signal pair through a transformer to the
media-dependent interface.
In 1000Base-T mode, transmit and receive occur simul-
taneously at TRD[0]±.
In 10Base-T and 100Base-TX modes, TRD[0]± are
used to transmit when operating in the MDI configura-
tion and to receive when operating in the MDI-X con-
figuration.
The PHY automatically determines the appropriate
MDI/MDI-X configuration.
Connect this signal pair through a transformer to the
media-dependent interface.
In 1000Base-T mode, transmit and receive occurs
simultaneously at TRD[1]±.
In 10Base-T and 100Base-TX modes, TRD[1]± are
used to receive when operating in the MDI configura-
tion and to transmit when operating in the MDI-X con-
figuration.
The PHY automatically determines the appropriate
MDI/MDI-X configuration.
Connect this signal pair through a transformer to the
media-dependent interface.
In 1000Base-T mode, transmit and receive occurs
simultaneously at TRD[2]±.
In 10Base-T and 100Base-TX modes, TRD[2]± are
unused.
Connect this signal pair through a transformer to the
media-dependent interface.
In 1000Base-T mode, transmit and receive occurs
simultaneously at TRD[3]±.
In 10Base-T and 100Base-TX modes, TRD[3]± are
unused.
RSET sets an absolute value reference current for the
transmitter.
Connect this signal to analog ground through a preci-
sion 6.34 kΩ 1% resistor.
