M52723ASP

DYNAMIC FOCUS

DESCRIPTION

The M52723ASP is semiconductor integrated circuit for Multi-Sync
display monitors.
It generates horizontal and vertical parabola waves, and it can
revise focus of CRT monitors.

FEATURES

It can control phase of horizontal wave.

•

It contains the horizontal saw wave generator and Auto Gain

•

Control circuit, so that it is able to keep the amplitude constant if
frequency change.

•

It change the parabola wave inretrace period to constant voltage
in order to reduce load at the amplitude after IC.

APPLICATION

CRT display monitor

RECOMMENDED OPERATING CONDITION
