DESCRIPTION
The M52737SP is a semiconductor integrated circuit amplifies video signals, having a 3-channel amplifier with a band width of 150MHz. 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, retrace blanking, wide-band amplification, contrast control (main and sub), and brightness control.

FEATURES
• Frequency band width:
    RGB................................150MHz (3VP-P)
    OSD..............................................50MHz
        Input :
            RGB.............................................................0.7VP-P (typ.)
            OSD...............................................3.0VP-P min. (positive)
            BLK (for OSD)...............................3.0VP-P min. (positive)
            Retrace BLK..................................3.0VP-P min. (positive)
        Output :RGB...........................................................4.5VP-P (max.)
            OSD...........................................................4.5VP-P (max.)
• To adjust contrast and OSD Adj, for each, two types of controls are provided, main and sub. With the main control, the contrast or OSD Adj of the 3-channels can be changed simultaneously. Sub controls are used to adjust the contrast of a given channel individually. The control terminals can be controlled by applying a voltage of 0 to 5V.
• The DC power remains stable at the IC output terminal because a feedback circuit is built in.

APPLICATION
    Display monitor
