ADV7188BSTZ

Overview

The ADV7188BSTZ is a multiformat SDTV video decoder by Analog Devices Inc. It supports NTSC, PAL, and SECAM standards. The device integrates four 12-bit Noise Shaped Video (NSV) ADCs operating at 54 MHz. It accepts CVBS, S-video, and component video inputs via 12 analog channels. Digital outputs support 8-bit, 10-bit, 16-bit, or 20-bit ITU-R BT.656 formats. Power supplies are 3.3 V analog and 1.8 V digital core. Operating temperature ranges from -40°C to +85°C. The package is an 80-lead Pb-free LQFP.

• Includes adaptive digital line length tracking for unstable sources
• Features 5-line adaptive comb filters for chrominance separation

Applications

• High end DVD recorders
• Video projectors
• HDD-based PVRs/DVDRs
• LCD TVs
• Set-top boxes

Procurement Notes

Verify the specific ordering suffix BSTZ against the manufacturer's current datasheet to confirm pinout and package details. Ensure compatibility with 3.3 V analog and 1.8 V digital supply requirements during system design. Confirm that the 80-lead LQFP footprint matches the target PCB layout constraints.

Selection Notes

Select this component when professional quality video performance with true 10-bit resolution is required in 10-bit output mode. It is suitable for applications needing simultaneous processing of CVBS and standard definition RGB signals. Consider its industrial temperature grade for environments requiring operation between -40°C and +85°C.

Part Context

This part belongs to the ADV7188 series of multiformat video decoders. It is designed to automatically detect and convert analog baseband television signals into digital ITU-R BT.656 format. The monolithic CMOS construction ensures lower power dissipation while providing extensive video processing features.

Replacement Considerations

Check the manufacturer's ordering guide for direct replacements or updated revisions within the ADV7188 family. Verify pin compatibility if substituting with other models in the same series.
