IC description
5-2. VPS 3215C(Video Processor)
(1) Descriptionincluding all substandards
The VPC 3215C is a high-quality, single-chip video front-- 1 composite, 1 S-VHS input, 1 composite output
end, which is targeted for 4:3 and 16:9, 100/120Hz TV- integrated high-quality A/D converters and associated
sets.clamp and AGC circuits
It can be conbined with other members of the DIGIT3000- multi-standard sync processing
IC family (such as CIP 3250A, DDP 3300A, TPU 3040)- linear horizontal scaling (0.25 ... 4), as well as non-linear
