ADV7283BCPZ

Codecs Overview

The ADV7283BCPZ is a multiformat SDTV video decoder fabricated in a 1.8 V CMOS process, housed in a 32-lead, 5 mm × 5 mm LFCSP package. It features one 10-bit ADC with 4× oversampling per channel for CVBS, Y/C, and YPrPb modes. The device supports NTSC, PAL, and SECAM standards via automatic detection. Power supplies AVDD, DVDD, and PVDD operate between 1.71 V and 1.89 V, while DVDDIO ranges from 1.62 V to 3.63 V. It includes an integrated interlaced-to-progressive converter (deinterlacer), adaptive contrast enhancement, and Rovi copy protection detection.

Codecs Feature Summary

• Supports worldwide NTSC, PAL, and SECAM color demodulation with automatic standard detection.
• Converts analog video signals into an 8-bit ITU-R BT.656 compatible YCrCb 4:2:2 data stream.
• Integrates an interlaced-to-progressive video output converter without requiring external memory.
• Includes a five-line adaptive 2D comb filter and chroma transient improvement processor.

Codecs Applications

• Automotive infotainment systems
• Smartphone and multimedia handsets
• Digital video recorders for security applications

Codecs Procurement Notes

Verify the specific suffix against official documentation to confirm temperature grade and qualification status. Confirm that the ordering code matches the required automotive or industrial specifications. Ensure compatibility with the intended power supply sequencing and I2C interface levels before procurement.

Codecs Selection Notes

Select this component when differential or single-ended analog video inputs require direct conversion to digital formats. The integrated deinterlacer simplifies designs by eliminating external memory requirements. Verify that the system can accommodate the specified power-up sequence involving DVDDIO followed by core supplies.

Codecs Part Context

This part belongs to the ADV7283 family of video decoders designed for standard definition television signals. It shares functional similarities with other members of the series but offers specific packaging and qualification options. The device is manufactured by Analog Devices Inc. using a specialized low-voltage CMOS process.

Codecs Replacement Considerations

Consult official substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. Ensure any replacement maintains support for the required video standards and interface protocols.

Codecs FAQ

How does the ADV7283 handle common-mode noise on video lines?

The device provides up to a 4 V common-mode input range solution when used with differential inputs, offering excellent rejection capabilities for large signal transients.

What is the function of the Adaptive Digital Line Length Tracking feature?

ADLLT allows the decoder to track and decode poor quality video sources, such as those from VCRs, by managing time-base correction and FIFO operations.

Can the ADV7283 detect copy protection signals?

Yes, it includes circuitry to identify and report Type I, Type II, and Type III Rovi (Macrovision) protection levels.
