GND for the PLL
Connected to 3.3v power and used as the
+1.8V Power from the internal PLL regulator.
This pin must be connected to a 10uF capacitor
(<2 Ohm ESR), in parallel with a 0.01uF
capacitor to ground. This pin must not be used
to supply power to other external devices. See
Note
reference voltage for the internal PLL
Ground for internal PLL reference voltage
Transmit Clock: 25MHz in 100Base-TX mode.
2.5MHz in 10Base-T mode.
Transmit Data 3-0: Data bits that are accepted
by the PHY for transmission.
When the internal PHY is selected, these
signals are driven low (0).
Transmit Enable: Indicates that valid data is
presented on the TXD[3:0] signals, for
transmission.
When the internal PHY is selected, this signal
is driven low (0).
Receive Clock: 25MHz in 100Base-TX mode.
2.5MHz in 10Base-T mode.
Receive Error: Asserted by the PHY to indicate
that an error was detected somewhere in the
frame presently being transferred from the PHY.
MII Collision Detect: Asserted by the PHY to
indicate detection of collision condition.
Receive Data 3-0: Data bits that are sent from
the PHY to the Ethernet MAC. See
Carrier Sense: Indicates detection of carrier.
Receive Data Valid: Indicates that recovered
and decoded data nibbles are being presented
by the PHY on RXD[3:0].
