Differential outputs providing reference clocks for IEEE
PHY conformance verification. For prototype testing, connect each pair to two-pin
headers. For production systems, leave pins unconnected.
THERM_Dp
THERM_Dn
O
Thermal Diode Reference.
Can be used to measure the Si temperature.
TEST_EN
I
Factory Test Pin.
Attach a 1 K
pull-down resistor to ground for normal
operation.

Name and Function
VCC33
P
3.3V Digital Power Supply.
For I/O circuits.
VCC18
P
1.8V Analog Power Supply.
For PHY analog, PHY I/O, PCI Express analog, and Phase Lock
Loop circuits, Connect all 1.8V pins to a single power supply.
VCC11
P
1.1V Digital Power Supply.
For core digital, PHY digital, PCI Express digital and clock
circuits, connect all 1.1V pins to a single power supply.

Name and Function
VSSA
P
Analog Ground.
Connects to PHY analog circuits. Connect directly to analog ground.
VSS
P
Digital Ground.
Connects to core and digital I/O. Connect to GND.
RSVD_ pin#
P
Reserved Pin.
These pins are reserved by Intel and may have factory test functions. For normal
operation, do not connect any circuitry to these pins (allow them to “float”). Some special
configurations may require pull-up or pull-down resistors on these pins. Please refer to the
82571EB/82572EI design guide for more information.
NC_pin#
P
No Connect.
This pin is not connected internally.
