3-CHANNEL VIDEO PREAMPLIFIER WITH OSD MIXING, RETRACE BLANKING

DESCRIPTION

The M52738P is semiconductor integrated circuit for CRT display
monitor.
It includes OSD blanking function, OSD mixing, Wide-band
amplifier, Main and sub contrast controls, Brightness control
function.

FEATURES

Frequency Band Width :RGB............................130MHz (at -3dB)

•

Input :RGB.............................................................0.7V

OSD.......................................1.6V

OSD BLK...............................1.6V

Retrace BLK........................1.2V

Output :RGB...............................................................4V

•

Contrast and brightness can be controlled with a main control.
The Main control changes contrast or brightness of 3-channels

simultaneously. The sub control changes contrast of each
channel independently.
