TVP5146M2IPFPR

Encoders, Decoders, Converters Overview

The TVP5146M2IPFPR is a high-quality, single-chip digital video decoder manufactured by Texas Instruments. It digitizes and decodes NTSC, PAL, SECAM composite and S-video formats into component YCbCr, while supporting analog-to-digital conversion of component RGB and YPbPr signals. The device integrates four 10-bit, 30-MSPS analog-to-digital converters (ADCs) with programmable gain control. It features an I2C host port interface for configuration, a VBI data processor for teletext and closed caption extraction, and supports multiple output formats including 10-bit and 20-bit ITU-R BT.656 4:2:2 YCbCr.
