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 a vailable for each channel, including OSD
blanking, wide-band amplification, contrast control (main and sub),
and brightness control.

FEATURES

•

Frequency band width: RGB................................130MHz (3V

Input :RGB.............................................................0.7V

BLK ...............................................3.0V

P-P

min. (positive)

Output :RGB...........................................................4.0V

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.

ELECTRICAL CHARACTERISTICS TEST METHOD

1. Because a description of signal input pin and pulse input pin
switch numbers is already given in Supplementary Table, only
external power supply switch numbers are included in the notes
below.
Sub contrast voltages V4, V8 and V12 are always set to the
same voltage, therefore only V4 is referred to in Supplementary
Table.

Measuring conditions are the same as those used above, except
that the setting of V14 is changed to 2.5V as specified in
Supplementary Table. Increase the input signal amplitude gradually,

Voltage V16 is varied as described below:

1. Increase V16 gradually while inputting SG6 to pin 11 (7 or 3).
Measure the voltage when the top of the waveform output at
T.P21 (25 or 29) is distorted. The voltage is called V

TR1 (VTG1 or

VTB1). Next, decrease V16 gradually, and measure the voltage
when the bottom of the waveform output at T.P29 (25 or 21) is
distorted. The voltage is called V
