FUNCTION

DIAGRAM

Digital Ground. Ground for digital I/O

N/A

circuits and control logic.

PLL Supply. DC power supply

decoupling point for the PLL dividers,

phase detector, and charge pump. This

pin is connected to the output of the

regulator and to the PLL supplies. There

must be a 220nF capacitor to ground

from this pin to decouple (bypass) noise

and to stabilize the regulator.

See Pin 11 below.

Ground for the PLL dividers, phase

N/A

detector, and charge pump.

DC Power Supply Input to the VCO

N/A

voltage regulator. Must be connected to

RVQMIF (pin 27) or RVDMD (pin 29) via

decoupling network.

DC power supply decoupling point for the N/A

VCO. Connected to the output of the

VCO regulator. A 220nF capacitor must

be tied between this pin and ground to

decouple (bypass) noise and to stabilize

the regulator.

DC ground for VCO and LO circuits.

Ground return for the Receive RF input

VCCA

and Transmit RF output.
