ADV7182BCPZ

Overview

The ADV7182BCPZ is a 10-bit SDTV video decoder with differential inputs, manufactured by Analog Devices Inc. It supports worldwide NTSC, PAL, and SECAM standards, converting analog baseband signals into an 8-bit ITU-R BT.656 YCrCb 4:2:2 data stream. The device features a single 10-bit ADC with 4× oversampling per channel for CVBS, Y/C, and YPrPb modes. It includes four analog video input channels with on-chip antialiasing filters and supports fully differential, pseudo-differential, and single-ended CVBS inputs. The decoder operates on a single 1.8 V supply and utilizes a two-wire serial I2C-compatible interface for control.

Feature Summary

• Supports worldwide NTSC, PAL, and SECAM color demodulation with automatic standard detection.
• Features a five-line adaptive comb filter and CTI/DNR video enhancement for superior image quality.
• Includes integrated automatic gain control (AGC) with adaptive peak white mode and fast switch capability.
• Provides Rovi copy protection detection and full-featured VBI data slicing with teletext support.

Applications

• Automotive infotainment systems
• DVRs for video security
• Media players

Procurement Notes

Verify the specific suffix BCPZ to confirm package type and temperature grade against official documentation. Ensure DVDDIO voltage requirements align with system design, as it supports 1.8 V or 3.3 V logic levels. Confirm RoHS compliance status if required for your manufacturing process. Check for automotive qualification if deploying in vehicle environments. Always refer to the latest datasheet revision for accurate pinout and electrical specifications.

Selection Notes

Select this component when high-resolution 10-bit conversion is needed for standard definition video processing. It is suitable for applications requiring robust common-mode rejection without external amplifiers. Consider its low power consumption and single-supply operation for portable or battery-powered devices. The integrated TBC functionality makes it ideal for handling variable line lengths from sources like VCRs. Evaluate its compatibility with downstream MPEG encoders or LCD controllers via the BT.656 interface.

Part Context

The ADV7182 belongs to Analog Devices' family of SDTV video decoders designed for consumer and automotive electronics. It replaces older multi-chip solutions by integrating the analog front end, standard definition processor, and digital output interface onto a single chip. This integration reduces board space and simplifies design complexity while maintaining professional video performance standards for various global broadcast formats.

Replacement Considerations

The ADV7182A is software-compatible and shares the same pinout. Verify if the specific temperature grade or package variant meets your application requirements before substituting.
