TP TRANSMIT PAIR DRIVERS.
These four outputs constitute the
twisted-pair drivers, which have predistortion capabilities. The TDH/
TDH outputs generate the 10 Mb/s Manchester Encoded data. The
TDL/TDL outputs mirror the TDH/TDH outputs except for fat bit
occurrences (100 ns pulses). During the second half of a fat bit
(either high or low), the TDL/TDL outputs are inverted with respect
to TDH/TDH outputs. This signal behavior reduces the amount of
jitter by preventing overcharge on the twisted pair medium.

TP RECEIVE PAIR.
The differential twisted pair receiver. The
receiver pair is connected to the twisted pair medium and is driven
with 10 Mb/s Manchester encoded data.

TRANSMIT CLOCK.
A 10 MHz clock output tied directly to the
transmit clock pin of the Ethernet controller. Changes sense
depending on controller selected. Active low for Intel and Fujitsu
controller interfaces, active high for National and AMD interfaces.
Can drive one TTL load.

TRANSMIT DATA.
TTL input. NRZ serial data is clocked in on TxD
from the Ethernet controller. Connects directly to the transmit data
pin of the Ethernet controller.
RTS

I
REQUEST TO SEND.
TTL input. An active low input signal
synchronous to TxC which enables data transmission on the active
port. Changes sense depending on controller selected. Active low
for the Intel controller interface, active high for National, AMD, and
Fujitsu interfaces.
RxC

O
RECEIVE CLOCK.
A 10 MHz clock output tied directly to the
receive clock pin of the Ethernet controller. This clock is the
recovered clock from incoming data on the active port. Changes
sense depending on controller selected. Active low for Intel and
Fujitsu controller interfaces, active high for National and AMD
interfaces. Can drive one TTL load.
RxD

O
RECEIVE DATA.
Received NRZ data (synchronous to RxC) passed
to the Ethernet controller. Connect directly to the receive data pin of
the controller. Can drive one TTL load.
CRS

O
CARRIER SENSE.
Output that alerts the Ethernet controller that
data is present on the active port. Connects directly to the carrier
sense pin of the Ethernet controller. Changes sense depending on
controller mode selected. Active low for Intel controller interface,
active high for National, AMD, and Fujitsu interfaces. Can drive one
TTL load.
CDT

O
COLLISION DETECT.
Output that indicates presence of a collision.
Connects directly to the collision detect pin of the Ethernet
controller. Changes sense depending on controller selected. Active
low for Intel and Fujitsu controller interfaces, active high for National
and AMD interfaces. Can drive one TTL load.
