... DESCRIPTION M52722SP is a video amplifier provided with OSD mixing function, and a semiconductor IC having three channels of a built-in wideband 180MHz amplifier. Each channel has the functions of OSD blanking, OSD mixing, retrace line blanking, wideband amplifier, main and sub contrast control, and main brightness. Accordingly structured to best fi ...
