GENERAL DESCRIPTION

The SPT2110 is a high-performance video digital signal

processor for NTSC and PAL applications. It processes 9-bit

composite digitized video or two 9-bit component digitized

video signals. All internal processing is done at 9 or more bits.

The decoder outputs the image data in YCrCb (4:2:2) or RGB

(4:4:4) formats. This product has many advanced internal

features not found in other decoder products. These features

include full 9-bit processing, AGC on both luminance and

chrominance processing, exceptional picture quality con-

trols, complete timing generation and a simple MPU inter-

face. All these features provide for easy digital video design

and produce digital image data that is free from dot error and

color noise. The SPT2110 video decoder is ideal for compos-

ite or S-Video applications requiring high quality signal de-

coding.
