Management Data
This pin is in-out to PHY. When RC is low, this pin will be
tri-state.
Management Data Clock
This pin output 1 MHz clock to drive PHY and access
corresponding speed and duplex data through MDIO.
25M Clock Output For GMII port
FET Control Signal
The pin is used to control FET for 3.3 V to 1.8 V regulator.
Add 0.01 µf capacitor to GND.
TX Resistor
Add 1.1K %1(A1), 1K %1 (A2) resister to GND.

25M Crystal Input
25M Crystal Input. Variation is limited to +/- 50ppm.
25M Crystal Output
When connected to oscillator, this pin should be left
unconnected.
TEST Value
At normal application connects to GND.
Must Connected to GND
Alert LED Display
This pin will show the status of power-on-diagnostic and
broadcast traffic.
