Type
1, 2
Description
18
MII2_SPD
I
PU
Speed Select - MII 2.
This signal is sensed at power up,
hardware reset, and software reset. Selects operating speed of
the respective MII (MAC) interface.
High = 100 Mbps. Low = 10 Mbps.

207
208
MII2_RXD0
MII2_RXD1
MII2_RXD2
MII2_RXD3
O
Receive Data - MII 2.
The LXT98x0 transmits received data to
the controller on these outputs. Data is driven on the falling edge
of MII2_RXCLK.
204
MII2_RXDV
O
Receive Data Valid - MII 2.
Active High signal, synchronous to
MII2_RXCLK, indicates valid data on MII2_RXD<3:0>.
203
MII2_RXCLK
O
Receive Clock - MII 2.
MII receive clock for expansion port. This
is a 2.5 or 25 MHz clock derived from the CLK25 input (refer to
Table 11 on page 30
).
202
MII2_RXER
O
Receive Error - MII 2.
Active High signal, synchronous to
MII2_RXCLK, indicates invalid data on MII2_RXD<3:0>.
197
MII2_TXER
I
Transmit Error - MII 2.
MII2_TXER is a 100 Mbps-only signal.
The MAC asserts this input when errors occurs in the transmit
data stream. The LXT98x0 sends
Invalid Code Symbols
on the
line.
196
MII2_TXCLK
O
Transmit Clock - MII 2.
This is a 2.5 or 25 MHz clock derived
from the CLK25 input (refer to
Table 11 on page 30
).
195
MII2_TXEN
I
Transmit Enable - MII 2.
External controllers drive this input High
to indicate data is transmitted on the MII2_TXD<3:0> pins.
Ground this input if unused.
194
193
192
191
MII2_TXD0
MII2_TXD1
MII2_TXD2
MII2_TXD3
I
Transmit Data - MII 2.
External controllers use these inputs to
transmit data to the LXT98x0. The LXT98x0 samples
MII2_TXD<3:0> on the rising edge of MII2_TXCLK, when
MII2_TXEN is High.
188
MII2_COL
O
Collision - MII 2.
The LXT98x0 drives this signal High to indicate
a collision occurred.
187
MII2_CRS
O
Carrier Sense - MII 2.
Active High signal indicates LXT98x0 is
transmitting or receiving.
1. I = Input, O = Output, I/O = Input/Output, D = Digital, A = Analog, AI = Analog Input,
A I/O = Analog Input/Output, OD = Open Drain, OS = Open Source, PD = Pull Down, PU = Pull Up.
NC = No Clamp. Pad does not clamp input in the absence of power.
2. Pins are 5V tolerant, unless indicated.
