M662M36562F3P5FP

DESCRIPTION

M66235 is produced using the silicon gate CMOS process. It

is able to output clock input signal in sync with optional exter-

nal trigger input signal.

It features excellent synchronizing precision (jitter) over a

wide frequency band range.

FEATURES

• 5V single power supply (5V ±5%)

• Frequency band: 25 ~ 52MHz

• Synchronizing precision (jitter): ±3ns

• Output types

(1) Output of the same frequency as input clock, and its in-

version

(2) 1/2 divider clock output and its inversion

(3) One-shot pulse output

(4) Continuous clock output

• Noise in the positive direction to trigger input is removed by

built-in noise killer circuit

APPLICATION

Clock phase control for horizontal synchronization
