M52734SP

3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING

DESCRIPTION

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

FEATURES

•

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

OSD..............................................50MHz

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

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

OSD...........................................................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, V9 and V14 are always set to the same
voltage, therefore only V4 is referred to in Supplementary Table.

CC Circuit current

I

Measuring conditions are as listed in Supplementary Table.
Measured with an ammeter At test point A when SW1 is set to a.

Vomax Output dynamic range

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 V
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).

TR1 (VTG1 or

2. V oltage V

T (VTR, VTG and VTB) 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 .P25; VTG1, at T.P30, and VTB, at T.P35.
