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.
N/A
Ground return for the Receive RF input
VCCA
and Transmit RF output.
