Features  
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.  
Very high performance, low cost  
• Adaptive comb-based decoding  
• Multiple pin-compatible versions  
- 3-line, 2-line, and band-split  
- 8- and 10-bit processing  
• Internal digital linestores  
• Supports NTSC/PAL field and NTSC frame based  
decoding  
• Multiple input formats  
- CCIR-601/624 (D1), D2, CVBS, YC  
• Multiple output 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.
