CC
. Typically connected to
same supply level as μprocessor or baseband controller to enable programming at
low voltages.
Ground for Aux analog circuitry.
Auxiliary prescaler input. Small signal input from the VCO.
Ground for Aux digital, MICROWIRE, FoLD, and oscillator.
Aux internal charge pump output. For connection to a loop filter for driving the
input of an external VCO.
Power supply for Aux charge pump. Must be
≥
V
CC
.
Power supply voltage input for Aux analog, Aux digital, FoLD, and oscillator
circuits. Input may range from 2.7V to 5.5V. V
