STANDARD CLOCK GENERATOR
STANDARD CLOCK GENERATOR
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
