M52733SP
3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING
DESCRIPTION
The M52733SP 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 blanking function.
The circuit is most useful with high resolution displays that have
OSD, and its function are available for each channel, including OSD
blanking, wide-band amplification, contrast control (main and sub),
and brightness control.
FEATURES
• Frequency band width: RGB................................130MHz (3VP-P)
Input :RGB.............................................................0.7VP-P (typ.)
BLK ...............................................3.0VP-P min. (positive)
Output :RGB...........................................................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.
APPLICATION
Display monitor
RECOMMENDED OPERATING CONDITION
Supply voltage range....................................................11.5 to 12.5V
