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.

W14 Clamp pulse minimum width

Under the same conditions as given in V14th, reduce the SG5 pulse
width gradually, monitoring the output. Measure the SG5 pulse
width when the output reaches 0V.

1. Measuring conditions are as given in Supplementary Table.

2. Measure the pedestal voltage at room temperature.
The measured value is called P

DC1.

3. Measure the pedestal voltage at temperatures of -20°C and
85°C. The measured value is called, respectively, PDC2 and
PDC3.

4. PDCH=PDC1 - PDC2

V1th BLK input threshold voltage

1. Measuring conditions are as given in Supplementary Table.

2. Make sure that signals are not being output synchronously with
SG7 (blanking period).

3. Reduce the SG7 input level gradually, monitoring output.
Measure the SG7 level when the blanking period disappears.
The measured value is called V1th.
