Power supply voltage input for RF analog and RF digital circuits. Input
may range from 2.7V to 5.5V. V
CC
1 must equal V
CC
2. Bypass
capacitors should be placed as close as possible to this pin and be
connected directly to the ground plane.
Power Supply for RF charge pump. Must be
≥
V
CC
.
Internal charge pump output. For connection to a loop filter for driving
the input of an external VCO.
Ground for RF digital circuitry.
RF prescaler input. Small signal input from the VCO.
RF 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 some loss of sensitivity.
Ground for RF analog circuitry.
Oscillator input. The input has a V
CC
/2 input threshold and can be
driven from an external CMOS or TTL logic gate.
Ground for IF digital, MICROWIRE
, F
o
LD, and oscillator circuits.
Multiplexed output of the RF/IF programmable or reference dividers,
RF/IF lock detect signals and Fastlock mode. CMOS output (see
Programmable Modes).
High impedance CMOS Clock input. Data for the various counters is
clocked in on the rising edge, into the 22-bit shift register.
Binary serial data input. Data entered MSB first. The last two bits are
the control bits. High impedance CMOS input.
