Power supply for charge pump. Must be

CC
Internal charge pump output. For connection to a loop filter for driving the
voltage control input of an external oscillator.
Ground.
RF prescaler complimentary input. In single-ended mode, a bypass
capacitor should be placed as close as possible to this pin and be
connected directly to the ground plane. The LMX2324 can be driven
differentially when the bypass capacitor is omitted.
RF prescaler input. Small signal input from the voltage controlled oscillator.
No Connect
No Connect
Oscillator input. A CMOS inverting gate input. The input has a V
CC
/2 input
threshold and can be driven from an external CMOS or TTL logic gate.
No Connect
High impedance CMOS Clock input. Data is clocked in on the rising edge,
into the various counters and registers.
Binary serial data input. Data entered MSB first. LSB is control bit. High
impedance CMOS input.
Load Enable input. When Load Enable transitions HIGH, data is loaded
into either the N or R register (control bit dependent). See timing diagram.
No Connect
No Connect
CHIP Enable. A LOW on CE powers down the device asynchronously and
will TRI-STATE
the charge pump output.
Power supply voltage input. Input may range from 2.7V to 5.5V. Bypass
capacitors should be placed as close as possible to this pin and be
connected directly to the ground plane.
