ADV7180WBST48Z

Overview

The ADV7180WBST48Z is an automotive-qualified, 10-bit, 4× oversampling SDTV video decoder in a 48-lead LQFP package. It supports NTSC, PAL, and SECAM standards with composite, S-Video, and component inputs. The device features three analog input channels, integrated AGC, Macrovision detection, and VBI data slicing. It outputs 8-bit ITU-R BT.656 YCrCb 4:2:2 data via I2C control. Operating voltage ranges from 1.71 V to 1.89 V for analog supplies, with digital I/O supporting 1.8 V to 3.3 V. Industrial temperature grade covers -40°C to +85°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for harsh environments
• Integrated 10-bit ADC with adaptive comb filters for superior chrominance separation
• Supports worldwide NTSC, PAL, and SECAM autodetection and conversion
• Includes Mini-TBC functionality via ADLLT for tracking varying line lengths

Applications

• In-car infotainment units
• Rearview camera systems
• Vehicle safety systems
• Digital camcorders

Procurement Notes

Verify the specific suffix 'W' confirms automotive qualification status. Confirm the 'BST48' designation matches the required 48-lead LQFP package dimensions. Ensure the ordering code includes the correct tape and reel packaging if applicable. Cross-reference the manufacturer's latest datasheet revision for any pinout or electrical characteristic updates before finalizing procurement specifications.

Selection Notes

Select this part when automotive reliability is mandatory alongside standard definition video decoding. The 48-lead LQFP offers a balance of pin count and thermal performance compared to smaller LFCSP options. Verify that the system requires 8-bit parallel output rather than the 16-bit mode available on the 64-lead variant. Ensure the design accommodates the single 1.8 V analog supply requirement.

Part Context

This component belongs to the ADV7180 family of multiformat video decoders. It shares core processing capabilities with other variants like the ADV7180BSTZ but differs in package type and qualification level. The 48-lead LQFP provides a compact footprint suitable for space-constrained automotive PCB layouts while maintaining robust thermal dissipation characteristics for industrial operating ranges.

Replacement Considerations

The ADV7180BSTZ serves as a commercial-grade alternative with identical pinouts but lacks automotive qualification. For higher channel counts, consider the ADV7181 series. Direct substitution requires verifying that the application does not strictly mandate AEC-Q100 certification.
