this pin and be connected directly to the ground plane.
Power supply for RF1 charge pump. Must be ≥ V
RF1 charge pump output. For connection to a loop filter for driving
the input of an external VCO.
LMX2335L: Ground for RF1 analog and RF1 digital circuits.
LMX2336L: Ground for RF digital circuits.
RF1 prescaler input. Small signal input from the VCO.
RF1 prescaler complementary input. A bypass capacitor should
be placed as close as possible to this pin and be connected
directly to the ground plane. Capacitor is optional with loss of
some sensitivity.
Ground for RF1 analog circuitry.
