TVP5146PFP

Product Summary

The TVP5146PFP is a high-quality, single-chip digital video decoder that converts baseband analog NTSC, PAL, and SECAM video into digital component video. Analog component, composite, and S-video inputs are supported. The TVP5146PFP includes two 10-bit oversampling A/D converters. Line-locked sampling is square-pixel or ITU-R BT.601 (27 MHz). The TVP5146PFP utilizes Texas Instruments’ patented technology for locking to weak, noisy, or unstable signals, and a chroma frequency control output is generated for synchronizing downstream video encoders. The applications of the TVP5146PFP are Digital television, Digital image processing, Video conferencing, Multimedia, Digital video, Desktop video1–3, Video capture, Video editing, Professional video applications, Security applications.
