TVP5146PFP

Encoders, Decoders, Converters Overview

The TVP5146PFP is a high-quality, single-chip digital video decoder manufactured by Texas Instruments. It digitizes and decodes NTSC, PAL, SECAM composite and S-video into component YCbCr, as well as analog component RGB and YPbPr signals. The device features four 10-bit 30-MSPS A/D converters with programmable gain control. It supports multiple output formats including 10-bit and 20-bit ITU-R BT.656 4:2:2 YCbCr with embedded or separate syncs. The unit includes a VBI data processor for teletext and closed captioning, an I2C host interface, and operates within a temperature range of 0°C to +70°C in an 80-pin HTQFP package.
