TEST
Test
Input, Active HIGH
This pin should be tied HIGH for normal operation. If
this pin is driven LOW, TPEX will enter Loopback Test
mode. The type of loopback is determined by the state
of the SQE TEST pin. If this pin is in the LOW state
(Station MAU), TPEX transfers data independently
from DO to the TXD/TXP circuit and from RXD to the DI
circuit. If the SQE TEST is in the HIGH state (Repeater
MAU), then data on the RXD circuit is transmitted back
onto the TXD/TXP circuit and data on the DO circuit is
transmitted onto the DI pair.
TXD+, TXD–
Transmit Data
Output
10BASE-T port differential drivers.
TXP+, TXP–
Transmit Predistortion
Output
Transmit waveform predistortion control.
XMT
Transmit
Output
This pin is driven HIGH while TPEX is receiving data on
the AUI DO pair and is transmitting data on the TXD/
TXP pins. The XMT and RCV pins are simultaneously
driven HIGH during collision.
