Power supply voltage input. Input may range from 2.7V to 5.5V. V
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
Internal charge pump output. For connection to a loop filter for driving the input of an external V
Ground.
RF prescaler input. Small signal input from the V
RF prescaler complimentary 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.
Oscillator input. The input has a V
or TTL logic gate.
Ground.
Multiplexed output of the RF/lF programmable or reference dividers, RF/lF 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 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.
IF prescaler complimentary 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.
IF prescaler input. Small signal input from the V
Ground.
IF charge pump output. For connection to a loop filter for driving the input of an external V
Power Supply for IF charge pump. Must be >V
Power supply voltage input Input may range from 2.7V to 5.5V. V
capacitors should be placed as close as possible to this pin and be connected directly to the ground
plane.
