TVP5146PFPR

Encoders, Decoders, Converters Overview

The TVP5146PFPR 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. Operating conditions range from 0°C to +70°C. The unit utilizes an 80-HTQFP package with a 12x12 mm footprint.

Encoders, Decoders, Converters Feature Summary

• Includes four 10-bit 30-MSPS A/D converters with analog preprocessors for signal clamping and gain adjustment
• Features adaptive 2-D, 5-line comb filtering and chroma trap filters for composite video processing
• Integrates a VBI data processor capable of parsing teletext, closed caption, and other vertical blanking interval data
• Provides fast-switch input support for pixel-by-pixel switching between CVBS and component video inputs

Encoders, Decoders, Converters Applications

• Digital monitors
• Television sets
• Video capture devices

Encoders, Decoders, Converters Procurement Notes

Verify the current lifecycle status before design implementation, as this component may be marked as Not Recommended for New Designs (NRND). Confirm that the 80-HTQFP package dimensions align with the target PCB layout. Ensure the host system provides the required 1.8V and 3.3V power rails and a 14.31818-MHz reference crystal for proper clock generation.

Encoders, Decoders, Converters Selection Notes

Select this decoder when multi-standard support for NTSC, PAL, and SECAM is required alongside component video decoding. Consider the integrated VBI data processor if teletext or closed caption extraction is necessary without external logic. Verify that the 10-bit or 20-bit parallel output interface matches the downstream processor's input capabilities.
