It accepts line-locked or subcarrier- locked composite, YC, or D1 digital video and produces dig- ital components in a variety of formats. An internal three-line adaptive comb decoder structure pro- duces 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 programma- bility 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 decod- ers in 8-bit and 10-bit versions—all in a pin and software- compatible format. Serial and parallel control ports are pro- vided. These submicron CMOS devices are packaged in a 100-lead Metric Quad Flat Pack (MQFP).
