DESCRIPTION

M52337SP is a video preamplifier provided with OSD mixing function, and a semi-conductor IC having three channels of a built-in amplifier in the 110MHz band.

Each channel has the functions of OSD blanking, OSD mixing, wideband amplifier, main and sub-contrast control, and main and sub brightness. Accordingly, it is structured to best fit the OSDprovided high-resolution display.

FEATURES

? 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)

? 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.

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

IC output pins.

? Pin arrangement of M52337SP is the same as that of M52321SP.
