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
Rated supply voltage................................................................12.0V

∆VCR2 Contrast control relative characteristics (minimum)
1. Measuring conditions are as given in Supplementary Table.
The setting of V14 is changed to 1.0V.
2. Measure the amplitude output at T.P21 (25 or 29). The measured
value is called VOR3 (VOG3 or VOB3), and is treated as VCR2.
3. Contrast control relative characteristics ∆VCR2 are calculated by
the equation below:
∆VCR2=VOR3/VOG3, VOG3/VOB3, VOB3/VOR3
VB1 Brightness control characteristics (maximum)
∆VB1 Brightness control relative characteristics (maximum)
1. Measuring conditions are as given in Supplementary Table.
2. Measure the output at T.P21 (25 or 29) with a voltmeter.
The measured value is called VOR7 (VOG7 or VOB7), and is treated
as VB1.
3. To obtain brightness control relative characteristics, calculate the
difference in the output between the channels, using VOR7, VOG7
and VOB7.

1. Set V4, V8 and V12 to 4.0V. Other conditions are as given in
Supplementary Table.
2. Measure the amplitude output at T.P21 (25 or 29). The measured
value is called VOR4 (VOG4 or VOB4).
