M52738P
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)
OSD.............................................80MHz
Input :RGB.............................................................0.7VP-P (typ.)
OSD.......................................1.6VP-P minimum (positive)
OSD BLK...............................1.6VP-P minimum (positive)
Retrace BLK........................1.2VP-P maximum (negative)
Output :RGB...............................................................4VP-P (min.)
OSD...............................................................4VP-P (min.)
• 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.
