44
TXD3
TXD2
TXD1
TXD0
I
Transmit Data.
TXD is a group of parallel data signals that are driven by the MAC.
TXD[3:0] transition synchronously with respect to TX_CLK.
TXD[0] is the least-significant bit.
43
TX_EN
I
Transmit Enable.
The MAC asserts this signal when it drives valid data on TXD.
This signal must be synchronized to TX_CLK.
42
TX_CLK
O
Transmit Clock.
TX_CLK is sourced by the PHY in both 10 and 100 Mbps
operations.
2.5 MHz for 10 Mbps operation
25 MHz for 100 Mbps operation.

RXD3
RXD2
RXD1
RXD0
O
Receive Data.
RXD is a group
of parallel signals that transition synchronously with
respect to RX_CLK.
RXD[0] is the least-significant bit.
37
RX_DV
O
Receive Data Valid.
The LXT972M Transceiver asserts this signal when it drives valid
data on RXD.
This output is synchronous to RX_CLK.
41
RX_ER
O
Receive Error.
Signals a receive error condition has occurred.
This output is synchronous to RX_CLK.
40
RX_CLK
O
Receive Clock.
25 MHz for 100 Mbps operation.
2.5 MHz for 10 Mbps operation.
For details, see
“Clock Requirements” on page 28
in
Chapter 5.0,
“Functional Description”
.
48
COL
O
Collision Detected
.
The LXT972M Transceiver asserts this output when a collision is
detected.
This output remains High for the duration of the collision.
This signal is asynchronous and is inactive during full- duplex
operation.
1
CRS
O
Carrier Sense
.
During half-duplex operation (Register bit 0.8 = 0), the LXT972M
Transceiver asserts this output when either transmitting or receiving
data packets.
During full-duplex operation (Register bit 0.8 = 1), CRS is asserted
only during receive.
CRS assertion is asynchronous with respect to RX_CLK. CRS is
de-asserted on loss of carrier, synchronous to RX_CLK.
