3-CHANNEL VIDEO PREAMPLIFIER WITH OSD MIXING FUNCTION

FOR HIGH-RESOLUTION COLOR DISPLAYS

DESCRIPTION

M52337SP is a video preampliï¬er provided with OSD mixing

function, and a semi-conductor IC having three channels of a built-

in ampliï¬er in the 110MHz band.

Each channel has the functions of OSD blanking, OSD mixing,

wideband ampliï¬er, main and sub-contrast control, and main and

sub brightness. Accordingly, it is structured to best ï¬t the OSD-

provided high-resolution display.

FEATURES

â¢ Frequency band: RGB ...................................110MHz (at 3VP-P)

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

Input : RGB...........................................................0.7VP-P (Typ.)

OSD.............................3.0 to 5.0 VP-P (positive polarity)

BLK..........................4.0 VP-P or more (positive polarity)

Output : RGB........................................................4.0 VP-P (max.)

OSD..............................3.5 VP-P (max., black level=2V)

â¢ Each control of contrast and brightness includes a main which

allows three 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.

â¢ A built-in feedback circuit inside IC provides a stable DC level at

IC output pins.

â¢ Pin arrangement of M52337SP is the same as that of M52321SP.
