DIGITAL VIDEO ENCODER FOR VIDEOCD

GENERAL DESCRIPTION

The SPCA711A is designed specifically for VideoCD, video games and other digital video systems, which

require the conversion of digital YCrCb (MPEG) data to analog NTSC/PAL video. The device supports a glue-

less interface to most popular MPEG decoders. The SPCA711A supports worldwide video standards, including

NTSC (N America, Japan) PAL-B, D, G, H, I (Europe, Asia), PAL-M (Brazil), PAL-N (Uruguay, Paraguay), and

PAL-Nc (Argentina). Furthermore, the SPCA711A operates with a single 2x clock and can be powered with a

single 3.3V supply. The composite analog video signal is output simultaneously onto two outputs. Therefore,

it allows one output to provide base-band composite video while the other drives a RF modulator. Alternatively,

analog luminance (Y) and chrominance (C) information is available for interfacing to S-video equipment. As a

slave, the SPCA711A automatically detects the input data formats (PAL/NTSC, CCIR601) and switches

internally to provide the proper format on the outputs. This feature, along with the on-board voltage reference

and single clock interface, makes the SPCA711A extremely simple to use. In addition, use of 2x over-sampling

on-chip simplifies external filter design resulting in reduced overall system cost.
