3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING
DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
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.

VCC1 (R)
• 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.

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.
3. After setting VTR (VTG or VTB), 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.
Sub contrast voltages V4, V8 and V12 are always set to the
same voltage, therefore only V4 is referred to in Supplementary
Table.
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,

Measuring conditions are as listed in Supplementary Table.
starting from 700mVP-P. Measure the amplitude when the output
signal starts becoming distorted.

Voltage V16 is varied as described below:
∆Gv Relative maximum gain
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 VTR1 (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 VTR2 (VTG2 or VTB2).
1. Input SG6 to pin 11 (7 or 3), and read the amplitude at output
T.P21 (25 or 29). The amplitude is called VOR1 (VOG1 or VOB1) .
2. Maximum gain GV is calculated by the equation below:

3. Contrast control characteristics VCR1 and relative characteristics
∆VCR1 are calculated, respectively, by the equations below:
Waveform Output at T.P21
(Identical to output at T.P25 and T.P29.)

Use relevant voltages, depending on the pin at which the
waveform is output; specifically, use VTR1 when it is output at
T.P21; VTG1, at T.P25, and VTB, at T.P29.

waveform amplitude output at T.P21 (25 or 29). The measured
value is called VOR, VOG and or VOB respectively.
1. Measuring conditions are as given in Supplementary Table.
2. Turn down the SG5 input level gradually, monitoring the output
(about 2.0 VDC). Measure the SG5 input level when the output
reaches 0V.
3. Crosstalk C.T. 1 is calculated by the equation below:
VOG or VOB
VOR
[VP-P]
[VP-P]
[dB]
C.T.1 =20LOG
(C.T.1')
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.
C.T.2 Crosstalk2 (f=50MHz)
C.T.2' Crosstalk2 (f=130MHz)
1. Change the input pin from pin 11 (R-ch) to pin 7 (G-ch), and
measure the output in the same way as in C.T.1, C.T.1'.
2. Crosstalk C.T. 2 is calculated by the equation below:
PDCH Pedestal voltage temperatere characteristics1
PDCL Pedestal voltage temperatere characteristics2
1. Measuring conditions are as given in Supplementary Table.
2. Measure the pedestal voltage at room temperature.
The measured value is called PDC1.
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
1. Change the input pin from pin 11 (R-ch) to pin 3 (B-ch), and
measure the output in the same way as in C.T.1, C.T.1'.
2. Crosstalk C.T. 3 is calculated by the equation below:
PDCL=PDC1 - PDC3

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

(C.T.3')
3. Reduce the SG7 input level gradually, monitoring output.
Measure the SG7 level when the blanking period disappears.
The measured value is called V1th.
