Description

The TMC22x5yA family of Digital Video Decoders offers unprecedented, broadcast-quality video processing performance in a single chip. It accepts line-locked or subcarrier locked composite, YC, or D1 digital video and produces digital components in a variety of formats.

An internal three-line adaptive comb decoder structure produces optimal picture quality with a wide range of source material. NTSC/PAL field and NTSC frame based decoding is supported with external memory. Full comb programmability allows the user to tailor the decoder’s response to a particular systems goals.

A family of products offers 3-line, 2-line, and simple decoders in 8-bit and 10-bit versions—all in a pin and software compatible format. Serial and parallel control ports are provided. These submicron CMOS devices are packaged in a 100-lead Metric Quad Flat Pack (MQFP).
