M52733SP
3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING
1
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.

·
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.
I
CC
Circuit current
Measuring conditions are as listed in Supplementary Table.
Measured with an ammeter At test point A when SW A is set to b.
Vomax Output dynamic range
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
(V
TG1
or
V
TB1
). 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
TR2
(V
TG2
or V
TB2
).
2. Voltage V
T
(V
TR
, V
TG
and V
TB
) is calculated by the equation
below:
Use relevant voltages, depending on the pin at which the
waveform is output; specifically, use V
TR1
when it is output at
T.P21; V
TG1
, at T.P25, and V
TB
, at T.P29.
3. After setting V
TR
(V
TG
or V
TB
), increase the SG6 amplitude
gradually, starting from 700mV. Measure the amplitude when the
top and bottom of the waveform output at T.P21 (25 or 29) starts
becoming distorted synchronously.
Vimax Maximum input
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,
starting from 700mV
P-P
.
Measure the amplitude when the output
signal starts becoming distorted.
Gv Maximum gain
Gv Relative maximum gain
1. Input SG6 to pin 11 (7 or 3), and read the amplitude at output
T.P21 (25 or 29). The amplitude is called V
OR1
(V
OG1
or V
OB1
) .
2. Maximum gain G

is calculated by the equation below:
3. Relative maximum gain

2. Measure the amplitude output at T.P21 (25 or 29). The measured
