Power and Ground Set
Repeat for Each PLL
VCCG & GNDG
The guard ring power and ground pins are called
PLL<PLL number>_VCCG and PLL<PLL number>_GNDG. The guard ring
isolates the PLL circuit from the rest of the device. Connect these guard
ring V
systems, this is the digital 1.5-V supply supplied to the device's V
pins. Connect the V
PLL. You can connect the GNDG pins directly to the same ground plane as
the device’s digital ground. See
