TVP5146M1PFP

Encoders, Decoders, Converters Overview

The TVP5146M1PFP 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 also supporting analog component RGB and YPbPr inputs. 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 captioning, and supports multiple output formats including 10-bit and 20-bit ITU-R BT.656 4:2:2 YCbCr.

Encoders, Decoders, Converters Feature Summary

• Integrates four 10-bit, 30-MSPS ADCs with analog preprocessors for robust signal conversion
• Includes adaptive 2-D, 5-line comb filtering and chroma trap filters for composite video processing
• Features a dedicated VBI data processor capable of parsing teletext, closed captioning, and VITC data
• Supports fast-switch input for pixel-by-pixel switching between CVBS and component video sources

Encoders, Decoders, Converters Applications

• Digital television receivers
• Video surveillance systems
• Set-top boxes and cable modems
• Video capture cards and grabbers

Encoders, Decoders, Converters Procurement Notes

Verify the specific ordering suffix M1PFP against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required I2C bus addressing and power supply voltages during system integration. Confirm that the design accounts for the moisture sensitivity level indicated in the mechanical data.

Encoders, Decoders, Converters Selection Notes

Select this component when multi-standard decoding of NTSC, PAL, and SECAM is required alongside component video support. The integrated VBI processor makes it suitable for applications needing direct extraction of teletext or closed captioning without external logic. Verify that the HTQFP-80 package fits the available PCB real estate and thermal constraints.
