3-CHANNEL VIDEO PREAMPLIFIER WITH OSD MIXING, RETRACE BLANKING
1
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 (3V
OSD..............................................50MHz
Input
:RGB.............................................................0.7V
OSD...............................................3.0V
BLK (for OSD)...............................3.0V
Retrace BLK..................................3.0V
Output :RGB...........................................................4.5V
OSD...........................................................4.5V
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.
