DDPLL
NOTE:
, V
SSPLL
Provides operating voltage and ground for the Phase-Locked Loop. This
allows the supply voltage to the PLL to be bypassed independently.
The VSSPLL pin should always be grounded even if the PLL is not used.
The VDDPLL pin should not be left floating. It is recommended to
connect the VDDPLL pin to ground if the PLL is not used.
PLL loop filter. Please see
information on how to calculate PLL loop filter elements. Any current
leakage on this pin must be avoided.
