Description
The TMC22x5yA family of Digital Video Decoders offers
unprecedented, broadcast-quality video processing perfor-
mance in a single chip. 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).
