PCB Layout Considerations

AVIN and PVIN should be tied together for optimal
performance. A local bypass capacitor should be placed
as close as possible to the PVIN pin.
GND should be connected to a ground plane with
multiple vias for improved thermal performance.

motherboard applications an ideal location would be at
the center of the termination bus.
VDDQ can be connected remotely to the VDDQ rail input
at either the DIMM or the Chipset. This provides the most
accurate point for creating the reference voltage.
