Overview
MITSUBISHI ICs (Monitor) 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.

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.
