M52737SP
3-CHANNEL VIDEO PREAMPLIFIER WITH OSD MIXING, RETRACE BLANKING
1
DESCRIPTION
The M52737SP is a semiconductor integrated circuit amplifies
video signals, having a 3-channel amplifier with a band width of
150MHz. 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, retrace blanking, wide-band amplification,
contrast control (main and sub), and brightness control.

·
To adjust contrast and OSD Adj, for each, two types of controls
are provided, main and sub. With the main control, the contrast or
OSD Adj 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.
I
CC
Circuit current
Measuring conditions are as listed in Supplementary Table.
Measured with an ammeter At test point A when SWA is set to b.
Vomax Output dynamic range
Voltage V19 is varied as described below:
1. Decrease V19 gradually while inputting SG5 to pin 13 (8 or 3).
Measure the voltage when the bottom of the waveform output at
T.P25 (30 or 35) is distorted. The voltage is called V
OLR
(V
OLG
or
V
OLB
).
2. Increase V19 gradually, and measure the voltage when the top
of the waveform output at T.P25 (30 or 35) is distorted. The
voltage is called V
OHR
(V
OHG
or V
OHB
).
3. Voltage V
OMAX
is calculated by the equation below:
V
OMAX
=V
OHR
(V
OHG
, V
OHB
)-V

(V

)

Vimax Maximum input
Voltage V17 is changed to 2.5V, and increase the input signal
amplitude gradually, starting from 700mV

.
Measure the amplitude when the output signal starts becoming
distorted.
