M52722SP
3-CHANNEL VIDEO PREAMPLIFIER PROVIDED WITH OSD MIX
AND RETRACE LINE BLK FOR HIGH-RESOLUTION
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 3VP-P )
OSD....................................................50MHz
Input:
RGB..........................................0.7VP-P (Typ.)
OSD......................................more than 3VP-P
(positive polarity)
BLK (for OSD)......................more than 3VP-P
(positive polarity)
Retrace line BLK..................more than 3VP-P
(positive polarity)
Output:
RGB..........................................4.0VP-P (max.)
OSD..........................................4.0VP-P (max.)
• 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.
APPLICATION
CRT display
RECOMMENDED OPERATING CONDITION
Supply voltage range...........................................Vcc=11.5 to 12.5V
Rated supply voltage......................................................Vcc=12.0V
