TVP5151IZQC

Overview

The TVP5151IZQC is an ultralow-power NTSC/PAL/SECAM video decoder manufactured by Texas Instruments. It converts analog baseband video signals into digital YCbCr 4:2:2 component video or ITU-R BT.656 format. The device features a single 9-bit analog-to-digital converter (ADC) with 2x sampling at 27 MHz, supporting composite and S-video inputs. It includes adaptive comb filtering for cross-luminance and cross-chrominance noise reduction. The decoder operates within an industrial temperature range of -40°C to +85°C and utilizes a 48-terminal PBGA package.

Feature Summary

• Supports NTSC, PAL, and SECAM video standards with a single 27-MHz crystal input
• Integrates a 9-bit ADC with automatic gain control and adaptive four-line comb filters
• Includes a VBI data processor for teletext, closed caption, and copy protection detection
• Configurable via I2C interface for brightness, saturation, hue, and sharpness adjustments

Applications

• Digital televisions
• Portable navigation devices
• Surveillance systems
• Video recorder/player units

Procurement Notes

Verify the specific suffix 'ZQC' corresponds to the 48-terminal PBGA package variant when sourcing. Confirm that the industrial grade designation 'I' matches the required operating temperature range of -40°C to +85°C for your application environment. Ensure compatibility with the host system's I2C voltage levels, as the IO_DVDD supports 1.8 V to 3.3 V.

Selection Notes

Select this component when designing systems requiring conversion of legacy analog video formats to digital interfaces. It is suitable for applications where power consumption is critical, given its ultralow-power architecture. Consider the 48-terminal PBGA package if space constraints on the PCB favor ball grid array configurations over TQFP packages.

Part Context

The TVP5151 series serves as a standard solution for decoding analog broadcast signals in embedded multimedia systems. It succeeds earlier models like the TVP5150AM1, offering improved robustness against weak or noisy signals. The device is part of Texas Instruments' broader portfolio of video processing ICs designed for consumer electronics and portable media devices.

FAQ

What clock frequency is required for the TVP5151?

The device requires a single 27.000-MHz crystal or oscillator input to generate the internal line-locked clock and sampling rates.

Does the TVP5151 support S-Video inputs?

Yes, the decoder supports either two selectable composite video inputs or one S-video input.

How is copy protection handled?

The device detects Macrovision copy-protected input signals, including Type 1, 2, 3, and colorstripe processes.
