Description
24
1
V
CC1
Power supply voltage input for RF analog and RF digital circuits. Input
may range from 2.7V to 5.5V. V
CC1 must equal VCC2. Bypass
capacitors should be placed as close as possible to this pin and be
connected directly to the ground plane.
22
V
P1
Power Supply for RF charge pump. Must be
≥ V
CC.
33
D
o RF
O
Internal charge pump output. For connection to a loop filter for driving
the input of an external VCO.
4
GND
Ground for RF digital circuitry.
55
f
IN RF
I
RF prescaler input. Small signal input from the VCO.
66
f
IN RF
I
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.
7
GND
Ground for RF analog circuitry.
8
OSC
in
I
Oscillator input. The input has a V
CC/2 input threshold and can be
driven from an external CMOS or TTL logic gate.
10
9
GND
Ground for IF digital, MICROWIRE,F
oLD, and oscillator circuits.
11
10
F
oLD
O
Multiplexed output of the RF/IF programmable or reference dividers,
RF/IF lock detect signals and Fastlock mode. CMOS output
(see
Programmable Modes).
12
11
Clock
I
High impedance CMOS Clock input. Data for the various counters is
clocked in on the rising edge, into the 22-bit shift register.
14
12
Data
I
Binary serial data input. Data entered MSB first. The last two bits are
the control bits. High impedance CMOS input.
