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

Common Ground
(100-LFBGA Package Only)
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].
