I
Oscillator input. The input has a V
CC
/2 input
threshold and can be driven from an external
CMOS or TTL logic gate.

GND
Ground for Aux digital, MICROWIRE, FoLD, and
oscillator circuits.
Multiplexed output of the Main/Aux
programmable or reference dividers,
Main/Auxiliary lock detect signals and Fastlock
mode. CMOS output (see Programmable Modes
in the Datasheet).

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.

Data
I
Binary serial data input. Data entered MSB first.
The last two bits are the control bits. High
impedance CMOS input.

LE
I
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).
