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.
Load enable high impedance CMOS input. When LE goes HIGH,
data stored in the shift registers is loaded into one of the 4
appropriate latches (control bit dependent).
Ground for IF analog circuitry.
IF 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.
