Transmit Clock
This input pin needs a continuous clock as timing reference for TXD[3:0] and
TXEN. TXC is supplied by the PHY. TXC is 2.5 MHz in 10 BASE-T nibble mode,
and 25MHz in 100BASE-TX nibble mode.
Transmit Enable
This output signal indicates the presence of a valid nibble data on TXD[3:0].
It becomes active when the first nibble data of the packet is valid on
TXD[3:0] and goes low after the last nibble data of the packet is clocked out
of TXD[3:0]. This signal connects directly to the PHY device. This signal is
active high.
Transmit Data
These pins transmit Nibble NRZ data to the PHY synchronously with TXC
when TXEN is asserted.
Receive Clock
This input pin needs a continuous clock as timing reference for RXDV and
RXD[3:0] signals. RXC is supplied by the PHY. RXC is 2.5MHz in 10BASE-T
nibble mode, and 25MHz in 100BASE-TX nibble mode.
Collision Detect
The active high signal at this input pin indicates that a collision has been
detected in Half-Duplex modes. This signal is asynchronous and is ignored
during full-duplex operation.
Carrier Sense
The active high signal at this input pin detects that carrier is present.
Receive Data Valid
If signal is detected high on this input pin, valid data is present on the
RXD[3:0]. If signal is detected low at the end of the valid packet, the signal
is valid on the rising of the RXC.
Receive Data
These pins receive Nibble NRZ data from the PHY device synchronously with
RXC when RXDV is asserted.
