AN5767K
Synchronizing signal processing IC
s Overview
The AN5767K is a synchronizing signal processing
IC with built-in frequency divider circuit for horizontal
and vertical synchronizing signal. Input signal is output-
ted after being devided by two.
s Features
• Built-in dividing-by-two circuit for horizontal synchro-
nizing signal
• Built-in dividing-by-two circuit for vertical synchroniz-
ing signal
• On/off switch function of dividing output
• Gain control function of dividing output
s Applications
• CRT monitors
