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.
