description

The TMS320AV420 is a video encoder that converts the RGB or YUV pixels to the analog S-video signal using digital-signal-processing techniques. The pixels are input to the 'AV420 using a 13.5-MHz clock. S-video is output from the 'AV420 on two separate RS170A-compatible analog channels, the luminance (Y) channel and the chrominance (C) channel. The 'AV420 operates in either interlaced or noninterlaced mode. The internal and external synchronization capabilities, vertical line interpolation, on-screen display, and direct interfacing features provide the 'AV420 video quality and facilitate video-system design.
