Small Footprint RMII 10/100 Ethernet Transceiver with HP Auto-MDIX Support
The MAC transmits data to the transceiver using
this signal.
The MAC transmits data to the transceiver using
this signal.
Indicates that valid transmission data is present
on TXD[1:0].
Bit 0 of the 2 data bits that are sent by the
transceiver on the receive path.
Combined with MODE1 and MODE2, this
configuration strap sets the default PHY mode.
See
configuration straps.
Note:
Bit 1 of the 2 data bits that are sent by the
transceiver on the receive path.
Combined with MODE0 and MODE2, this
configuration strap sets the default PHY mode.
See
configuration straps.
Note:
This signal is asserted to indicate that an error
was detected somewhere in the frame presently
being transferred from the transceiver.
This configuration strap sets the transceiver’s
SMI address.
