Analog Ground.
Ground Input/Output.
Ground return for digital I/O circuits (VCCIO).
MII Power.
Requires either a 3.3 V or a 2.5 V supply. Must be supplied
from the same source used to power the MAC on the other
side of the MII.
For the LXT972M Transceiver, VCCIO is 3.3 V.
Analog Power.
Requires a 3.3 V power supply.
Digital Power.
Requires a 3.3 V power supply.
No Connection.
These pins are not used and must not be terminated.
Test Data Input.
Test data sampled with respect to the rising edge of TCK.
Test Data Output.
Test data driven with respect to the falling edge of TCK.
Test Mode Select.
Test Clock.
Clock input for boundary scan.
Test Reset.
This active-low test reset input is sourced by ATE.
