... DESCRIPTION The M52734SP is a semiconductor integrated circuit amplifies video signals, having a 3-channel amplifier with a band width of 130MHz. The circuit also features the OSD mixing function. The circuit is most useful with high resolution displays that have OSD, and its function are available for each channel, including OSD blanking, OSD mixing, wide-band amplifi ...
