TVP5146M2PFPR

Encoders, Decoders, Converters Overview

The TVP5146M2PFPR 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 4:2:2 YCbCr with embedded or separate syncs. The unit operates within a temperature range of 0°C to +70°C and utilizes an 80-pin HTQFP package.

Encoders, Decoders, Converters Procurement Notes

Verify the specific ordering suffix PFPR to confirm the tape-and-reel packaging configuration before procurement. Confirm that the M2 variant designation aligns with the required hardware revision for your design. Ensure the 80-pin HTQFP footprint matches your PCB layout specifications. Check current availability status as this component may be subject to discontinuation notices.

Encoders, Decoders, Converters Selection Notes

Select this component when a single-chip solution is required for decoding standard definition analog video formats into digital component outputs. Verify compatibility with the host system's I2C interface requirements. Ensure the power supply voltages match the specified 1.8V and 3.3V rails. Consider the thermal dissipation capabilities of the PowerPAD QFP package for the target enclosure.

Encoders, Decoders, Converters Part Context

This part belongs to the TVP5146 family of video decoders from Texas Instruments. The M2 suffix typically denotes a specific manufacturing lot or minor hardware revision within the same functional family. It shares core architecture with the base TVP5146 model but may differ in internal ROM versions or specific silicon stepping characteristics documented in the manufacturer's errata.

Encoders, Decoders, Converters Replacement Considerations

TVP5146M2PFPR serves as a direct replacement for the standard TVP5146PFPR. Verify pinout compatibility and register settings when migrating between these variants.
