M52722SP
3-CHANNEL VIDEO PREAMPLIFIER PROVIDED WITH OSD MIX
AND RETRACE LINE BLK FOR HIGH-RESOLUTION
1
DESCRIPTION
M52722SP is a video amplifier provided with OSD mixing function,
and a semiconductor IC having three channels of a built-in
wideband 180MHz amplifier.
Each channel has the functions of OSD blanking, OSD mixing,
retrace line blanking, wideband amplifier, main and sub contrast
control, and main brightness. Accordingly, it is structured to best fit
the OSD-provided high resolution display. .
FEATURES
·
Frequency band : RGB...................................180MHz (at 3V
P-P
)
OSD....................................................50MHz
Input: RGB..........................................0.7V
P-P
(Typ.)
OSD......................................more than 3V

·
Each control of contrast and OSD adjustment includes a main
which allows 3 channels to be variable simultaneously, and a sub
which allows each channel to be variable independently. Each
control pin can be controlled within a range of 0 to 5V.
·
A built-in feedback circuit inside IC provides a stable DC level at
IC output pins.

ELECTRICAL CHARACTERISTICS
(cont.)
ELECTRICAL CHARACTERISTICS TEST METHOD
Note: SW/NO of signal input pin and SW/NO of pulse input pin,
which have already been described in the electrical characteristics
table, are omitted, and SW/NO of external power supply will only be
described as follows:
Sub-OSD adjustment voltages, V32, V27 and V22, which are
always set to the identical value, are represented by V32 in the
electrical characteristics table. In addition, sub-contrast voltages,
V4, V9 and V14, which are also set to the identical value, are
represented by V4 in the electrical characteristics table.
Icc circuit current
Conditions shall be as specified in the electrical characteristics
table, and take measurements with ammeter A when SWA is turned
to the b side.
Vomax output dynamic range
Follow the following procedure to set V19.
1. Input SG5 to pin
(pin
or pin
), gradually reduce V19, and
read the lower part voltage when the lower part of input
waveform of T.P25 (T.P30 or T.P35) is distorted to let the reading
be V
OLR
(V
OLG
or V
OLB
).
2. Then, gradually raise V19, and read the upper part voltage when
the upper part of output waveform of T.P25 (T.P30 or T.P35) is
distorted to let the reading be V
OHR
(V
OHG
or V
OHB
).
3. Vomax is found by:
Vomax=V
OHR
(V
OHG
, V
OHB
)-V
OLR
(V
OLG
, V
OLB
)
Vimax maximum allowable input
Change V17 to 2.5V, gradually increase input signal amplitude from
700m V
P-P
, and read input signal amplitude when output signal
starts to be distorted.
Gv and
Gv maximum gain and relative maximum gain
1. Input SG5 to pin
(pin
or pin
), and read the output
amplitude of T.P25 (T.P30 or T.P35) at this time to let the reading
be V
OR1
(V
OG1
or V
OB1
).
2. Maximum gain Gv is found by:

relative contrast control characteristics (at typ.)
1. Follow the electrical characteristics table except changing V17 to

2. Read the output amplitude of T.P25 (T.P30 or T.P35) at this time,
and let the reading be V
OR2
(V

).
3. Contrast control characteristics VCR1 and relative contrast

V
CR2
contrast control characteristics and
V

relative contrast control characteristics (at min.)
1. Follow the electrical characteristics table except changing V17 to

2. Read the output amplitude of T.P25 (T.P30 or T.P35) at this time
to let the reading be V
