VTT_VID[4:2]

VTT_VID[2:4] (VTT Voltage ID) are used to support automatic selection of power

supply voltages (V

VTT_SENSE
VSS_SENSE_VTT

O
O

VTT_SENSE and VSS_SENSE_VTT provide an isolated, low impedance

connection to the processor V

voltage and ground. They can used to sense or

measure voltage near the silicon.

VTTPWRGOOD

The processor requires this input signal to be a clean indication that the V

power supply is stable and within specifications. 'Clean' implies that the signal

will remain low (capable of sinking leakage current), without glitches, from the

time that the power supplies are turned on until they come within specification.

The signal must then transition monotonically to a high state. Note that it is not

valid for VTTPWRGOOD to be deasserted while VCCPWRGOOD is asserted.

Notes:

DDR{0/1/2} refers to DDR3 Channel 0, DDR3 Channel 1, and DDR3 Channel 2.
