Datasheet 

VTT_VID[4:2]

O

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

supply voltages (V

TT

). 

VTT_SENSE
VSS_SENSE_VTT

O
O

VTT_SENSE and VSS_SENSE_VTT provide an isolated, low impedance 

connection to the processor V

TT

 voltage and ground. They can be used to sense 

or measure voltage near the silicon.

VTTPWRGOOD

I

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

TT

 

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  de-asserted while VCCPWRGOOD is asserted.

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