(20TSSOP)

Pin No

(24QFN)

Symbol

I / O

Description

finIF

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.

finIF

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

GND

Ground for IF digital blocks.

CPoIF

Internal IF charge pump output for connection to an external

loop filter whose filtered output drives an external VCO.

N/C

No connection.

Vp2

Power supply voltage input for IF charge pump(

≥ VDD2)

VDD2

Power supply voltage input for the IF PLL part. VDD1 must

equal VDD2. 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.
