TVP5156PNP

Overview

The TVP5156PNP is a four-channel NTSC/PAL video decoder manufactured by Texas Instruments. It operates within a supply voltage range of 1.1 V, 1.8 V, and 3.3 V, with a typical operating current of 172 mA. The device supports an extended temperature range from 0°C to +70°C and utilizes an HTQFP-128 surface-mount package. This component converts analog composite or S-video signals into digital parallel output for further processing.

Feature Summary

• Integrates four independent video decoding channels for simultaneous signal processing
• Supports standard NTSC and PAL television signal formats
• Accepts both composite and S-video input configurations

Applications

• Security surveillance systems requiring multi-channel video capture
• Video conferencing equipment handling multiple camera inputs
• Digital video recorders (DVRs) for analog source integration

Procurement Notes

Verify the specific suffix PNPR against PNPA when sourcing, as packaging differs between reel and tray options. Confirm RoHS compliance status through official documentation prior to procurement. Ensure compatibility with the required 128-pin HTQFP footprint during PCB layout finalization.

Selection Notes

Select this model for applications requiring four distinct analog video inputs processed concurrently. Compare power consumption requirements against single-channel alternatives if fewer inputs are needed. Validate that the 1.1V to 3.3V supply rails align with the target system's power architecture.

Part Context

This part belongs to the TVP515x series of high-performance video decoders from Texas Instruments. It shares functional similarities with the TVP5158 and TVP5157 but is specifically configured for NTSC and PAL standards without SECAM support. It serves as a bridge between legacy analog video sources and modern digital processing architectures.

Replacement Considerations

TVP5158PNP offers similar functionality with potential format variations. TVP5157PNP provides comparable channel counts. Verify pinout compatibility and software register settings before substituting these related family members.
