TVP5145PFPU-1.3B

Product Summary

The TVP5145PFPU-1.3B 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 TVP5145PFPU-1.3B includes two 10-bit oversampling A/D converters. Line-locked sampling is square-pixel or ITU-R BT.601 (27 MHz). The TVP5145PFPU-1.3B 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 TVP5145PFPU-1.3B are Digital television, Digital image processing, Video conferencing, Multimedia, Digital video, Desktop video1–3, Video capture, Video editing, Professional video applications, Security applications.
