Description
Transmit Clock: This pin provides a continuous clock as a timing reference
for TXD[3:0] and TXEN.
Transmit Enable: The input signal indicates the presence of a valid nibble
data on TXD[3:0].
Transmit Data: MAC will source TXD[0..3] synchronous with TXC when
TXEN is asserted.
Receive Clock: This pin provides a continuous clock reference for RXDV
and RXD[0..3] signals. RXC is 25MHz in the 100Mbps mode and 2.5Mhz in
the 10Mbps mode.
Collision Detected: COL is asserted high when a collision is detected on the media.
Carrier Sense: This pin’s signal is asserted high if the media is not in IDEL state.
Receive Data Valid: This pin’s signal is asserted high when received data is
present on the RXD[3:0] lines; the signal is deasserted at the end of the
packet. The signal is valid on the rising of the RXC.
Receive Data: These are the four parallel receive data lines aligned on the
nibble boundaries driven synchronously to the RXC for reception by the
external physical unit (PHY).
Receive error: if any 5B decode error occurred such as invalid J/K, T/R,
invalid symbol, this pin will go high
Management Data Clock: This pin provides a clock synchronous to MDIO,
which may be asynchronous to the transmit TXC and receive RXC clocks.
Management Data Input/Output: This pin provides the bi-directional
signal used to transfer management information.
