3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING
DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
The M52734SP 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 mixing function.
The circuit is most useful with high resolution displays that have
OSD, and its function are available for each channel, including OSD
blanking, OSD mixing, 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.

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.
(V)
5.0
Sub contrast voltages V4, V9 and V14 are always set to the same
voltage, therefore only V4 is referred to in Supplementary Table.
ICC Circuit current
Measuring conditions are as listed in Supplementary Table.

2. Voltage VT (VTR, VTG and VTB) is calculated by the equation
below:
Voltage V19 is varied as described below:
1. Increase V19 gradually while inputting SG6 to pin 13 (8 or 3).
Measure the voltage when the top of the waveform output at
T.P25 (30 or 35) is distorted.The voltage is called VTR1 (VTG1 or
VTB1). Next, decrease V19 gradually, and measure the voltage
when the bottom of the waveform output at T.P35 (30 or 25) is
distorted. The voltage is called VTR2 (VTG2 or VTB2).
VTR1 (VTG1, VTB1) + VTR2 (VTG1, VTB1)
VTR (VTG, VTB)=

Use relevant voltages, depending on the pin at which the
waveform is output; specifically, use VTR1 when it is output at
T.P25; VTG1, at T.P30, and VTB, at T.P35.
