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 amplification, contrast control (main and sub), and brightness control.

FEATURES

• Frequency band width: RGB................................130MHz (3VP-P)

OSD..............................................50MHz

Input :RGB.............................................................0.7VP-P (typ.)

OSD...............................................3.0VP-P min. (positive)

BLK ...............................................3.0VP-P min. (positive)

Output :RGB...........................................................4.0VP-P (max.)

OSD...........................................................4.0VP-P (max.)

• To adjust contrast, two types of controls are provided, main and

sub. With the main control, the contrast 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.
