TVP5154APNPR

Overview

The TVP5154APNPR is a four-channel low-power video decoder manufactured by Texas Instruments, housed in a 128-pin HTQFP PowerPAD package. It converts NTSC (J, M, 4.43), PAL (B, D, G, H, I, M, N, Nc), and SECAM (B, D, G, K, K1, L) composite or S-video signals into digital ITU-R BT.601/656 formats. Each channel features a 9-bit ADC with 2x sampling at 27 MHz or 54 MHz, driven by a single 14.31818-MHz crystal. The device operates on a 1.8-V analog/digital supply and a 3.3-V I/O supply, consuming approximately 700 mW. It supports independent scaling, VBI data processing, and fast lock modes within the commercial temperature range of 0°C to 70°C.

Feature Summary

• Four independent video channels with programmable polymorphic scalers for concurrent scaled and unscaled outputs.
• Patented architecture enabling robust locking to weak, noisy, or unstable video signals with improved fast lock capabilities.
• Integrated VBI data processor supporting teletext, closed caption, and wide-screen signaling extraction via I2C.
• Complementary 4-line adaptive comb filtering for cross-luminance and cross-chrominance noise reduction.

Applications

• Security and surveillance digital video recorders and servers
• Automotive infotainment video hubs
• Large-format video wall displays

Procurement Notes

Verify the specific ordering suffix PNPR indicates tape and reel packaging when sourcing this component. Confirm that the commercial grade variant meets the required operational temperature range of 0°C to 70°C for the target application environment. Ensure the host system provides the necessary 1.8-V and 3.3-V power rails as specified in the electrical characteristics.

Selection Notes

Select the TVP5154A series when multi-channel decoding of standard definition video is required with integrated scaling capabilities. Consider the industrial grade version if operation below 0°C is necessary. Verify that the 128-pin TQFP package footprint aligns with the PCB layout constraints and thermal management requirements of the design.

Part Context

This component belongs to the TVP5154A family of video decoders from Texas Instruments. It shares functional similarities with related models such as the TVP5150 and TVP5151 but offers higher channel density and advanced scaling features. The APNPR designation specifically denotes the commercial temperature range and tape-and-reel packaging format.
