finIF
I
The complementary input of the IF prescaler. A bypass
capacitor must be placed as close as possible to this pin and
be connected directly to the ground plane. The bypass
capacitor is optional with some loss of sensitivity.
16

finIF
I
IF prescaler input. The signal comes from the external VCO.

GND
-
Ground for IF digital blocks.

CPoIF
O
Internal IF charge pump output for connection to an external
loop filter whose filtered output drives an external VCO.

2. In order to reject supply noise, bypass capacitors
must be placed as close as possible to this pin and be
connected directly to the ground plane.
