Description

VDDQ

K20

PWR

Quiet VDD for the PLL Subsystem. Should be supplied from VDD

through a low-Q series inductor. It should be bypassed for AC to VSSQ,

using a dual capacitor bypass (high and low frequency AC bypass).

VSSQ

L19

GND

Quiet VSS for the PLL Subsystem. ShouldbeAC bypassed toVDDQ,

otherwise left DC floating. It is connected on-chip to VSS.Noexternal

coil or other connection to board ground is needed; such a connection

would create a ground loop.
