TVP5157PNPR

Overview

The TVP5157PNPR is a four-channel NTSC/PAL video decoder manufactured by Texas Instruments. It digitizes analog composite and S-video signals using four independent 10-bit, 27-MSPS analog-to-digital converters (ADCs). The device operates with supply voltages of 1.1 V, 1.8 V, and 3.3 V, drawing a typical operating current of 172 mA. Designed for surface-mount installation, it utilizes a 128-lead HTQFP package. The component supports standard digital video output formats including ITU-R BT.656 8-bit 4:2:2 and 16-bit 4:2:2 with embedded synchronization.

Feature Summary

• Four independent decoding channels supporting composite and pseudo-differential video inputs to enhance noise immunity.
• Integrated high-speed 10-bit ADCs combined with anti-aliasing filters for precise signal sampling.
• Built-in video processing capabilities including noise reduction and automatic contrast adjustment.
• Programmable control over hue, saturation, sharpness, brightness, and contrast parameters.

Applications

• Digital video surveillance systems
• Video capture cards and dongles
• Set-top boxes and media players

Procurement Notes

Verify the specific suffix PNPR against the manufacturer datasheet to confirm the tape-and-reel packaging configuration. Ensure the design accommodates the required 1.1 V, 1.8 V, and 3.3 V power domains. Confirm that the 128-lead HTQFP footprint matches the PCB layout specifications before finalizing procurement.

Selection Notes

Select this model when four-channel simultaneous decoding is required without integrated audio conversion. Compare against the TVP5158 if onboard audio ADCs are necessary for the application. Verify that the 27-MSPS sampling rate meets the bandwidth requirements for the target NTSC or PAL standards.

Part Context

This component belongs to the TVP515x family of video decoders from Texas Instruments. It shares architectural similarities with the TVP5158 and TVP5156 but lacks the integrated audio ADCs found in those variants. The device serves as a bridge between legacy analog video sources and modern digital processing units.

Replacement Considerations

The TVP5158PNPR offers identical video decoding performance but includes integrated audio ADCs. Designers requiring audio integration should consider this alternative. Other family members like the TVP5156 may offer different feature sets or pin configurations.
