M52742ASP
BUS CONTROLLED 3-CHANNEL VIDEO PREAMP FOR CRT DISPLAY MONITOR
DESCRIPTION
M52742ASP is semiconductor integrated circuit for CRT display
monitor.
It includes OSD blanking, OSD mixing, retrace blanking, wide band
amplifer, brightness control, uniformity function.
Main/sub contrast and OSD adjust function can be controlled by I²C
bus.
