ADV7180BSTZ

Overview

The ADV7180BSTZ is a 64-lead LQFP SDTV video decoder supporting NTSC, PAL, and SECAM standards. It features one 10-bit ADC with 4× oversampling for CVBS and 2× for Y/C or YPrPb inputs. The device provides 6 analog video input channels and outputs 8-bit/16-bit ITU-R BT.656 data. Operating at 1.8 V supplies, it includes integrated AGC, comb filters, and Macrovision detection. Qualified to AEC-Q100, it functions within a -40°C to +85°C temperature range.

Feature Summary

• Automatically detects and converts worldwide NTSC, PAL, and SECAM baseband signals into digital ITU-R BT.656 format.
• Integrates a single high-speed 10-bit ADC with differential channels and on-chip antialiasing filters for three video input channels.
• Includes five-line adaptive comb filters, CTI/DNR enhancement, and Mini-TBC functionality via ADLLT for signal tracking.
• Supports full-featured VBI data slicing for teletext and closed captioning, alongside Macrovision copy protection detection.

Applications

• Digital camcorders and PDAs
• Low cost SDTV PIP decoders for digital TVs
• Multichannel DVRs for video security
• AV receivers and video transcoding
• In-car/automotive infotainment units

Procurement Notes

Verify the specific package type matches the design requirements, as the ADV7180 series offers multiple options including 32-lead LFCSP, 40-lead LFCSP, 48-lead LQFP, and 64-lead LQFP. Confirm that the temperature grade aligns with the application environment, noting that the BSTZ suffix indicates an industrial/automotive qualified range of -40°C to +85°C. Ensure I2C address selection via the ALSB pin is compatible with the system bus configuration.

Selection Notes

Select the ADV7180BSTZ when a 64-lead LQFP package is required for space or thermal management reasons compared to smaller LFCSP options. This variant supports both 8-bit and 16-bit parallel output interfaces, offering greater flexibility for connecting to various MPEG encoders or mobile video processors. Choose this part if the application demands AEC-Q100 qualification for automotive environments while maintaining compatibility with standard consumer video sources.

Part Context

The ADV7180BSTZ belongs to the ADV7180 family of multiformat video decoders manufactured by Analog Devices. It is designed to replace older discrete decoding solutions by integrating analog front-end processing, digitization, and digital video filtering into a single CMOS chip. The 64-lead LQFP package distinguishes it from the more compact LFCSP variants, providing additional pins for expanded digital I/O and general-purpose outputs.

Replacement Considerations

The ADV7180WBSTZ serves as the automotive qualified replacement with an extended temperature range up to +125°C. For applications requiring fewer pins, the ADV7180BCPZ (40-lead LFCSP) is a pin-compatible alternative for 3-channel inputs but lacks the 16-bit output capability of the 64-lead version.
