Electrical Specifications
7.1
Power and Ground Pins
The processor has VCC, VCCIO, VDDQ, VCCPLL, VCCSA, VAXG, and VSS (ground) 
inputs for on-chip power distribution. All power pins must be connected to their 
respective processor power planes, while all VSS pins must be connected to the system 
ground plane. Use of multiple power and ground planes is recommended to reduce I*R 
drop. The VCC pins and VAXG pins must be supplied with the voltage determined by 
the processor Serial Voltage IDentification (SVID) interface. 
 specifies the 
voltage level for the various VIDs.
7.2
Decoupling Guidelines
Due to its large number of transistors and high internal clock speeds, the processor is 
capable of generating large current swings between low- and full-power states. To keep 
voltages within specification, output decoupling must be properly designed.
Caution:
Design the board to ensure that the voltage provided to the processor remains within 
. Failure to do so can result in timing violations or 
reduced lifetime of the processor.
7.2.1
Voltage Rail Decoupling
The voltage regulator solution must:
• provide sufficient decoupling to compensate for large current swings generated 
during different power mode transitions.
• provide low parasitic resistance from the regulator to the socket.
• meet voltage and current specifications as defined in 
.
7.2.2
PLL Power Supply
An on-die PLL filter solution is implemented on the processor.
