ADV7180BST48Z

Overview

The ADV7180BST48Z is a 10-bit, 4× oversampling SDTV video decoder in a 48-lead LQFP package. It supports NTSC, PAL, and SECAM standards with CVBS, Y/C, and YPrPb inputs. The device features three analog video input channels, an integrated AGC, and a 5-line adaptive comb filter. It outputs 8-bit ITU-R BT.656 data via I2C control. Qualified for automotive applications under AEC-Q100, it operates from -40°C to +85°C.

Feature Summary

• Supports worldwide NTSC, PAL, and SECAM color demodulation with automatic standard detection.
• Includes a 10-bit ADC with 4× oversampling for composite video and 2× oversampling for component modes.
• Features a 5-line adaptive comb filter and CTI/DNR video enhancement capabilities.
• Provides Mini-TBC functionality through adaptive digital line length tracking.

Applications

• In-car/automotive infotainment units
• Rearview camera/vehicle safety systems
• Multichannel DVRs for video security

Procurement Notes

Verify the specific suffix 'BST48Z' corresponds to the 48-lead LQFP package and industrial temperature range. Confirm AEC-Q100 qualification status if required for automotive deployment. Ensure compatibility with the 1.8V supply voltage and I2C interface requirements during system integration.

Selection Notes

Select this model for applications requiring a 48-pin footprint with automotive-grade reliability. Compare against the 64-lead LQFP variant if additional digital output lines or pin compatibility with ADV7181C are necessary. Consider the 32- or 40-lead LFCSP options for space-constrained portable designs where fewer pins suffice.

Part Context

The ADV7180 series includes variants like the ADV7180BSTZ (64-lead) and ADV7180WBST48Z (automotive). The BST48Z suffix indicates the 48-lead LQFP package. This part converts analog baseband signals to digital ITU-R BT.656 format, serving as a bridge between legacy video sources and modern digital processors.

Replacement Considerations

The ADV7180WBST48Z is the automotive-qualified version of this component. For pin-compatible upgrades, consider the ADV7180BSTZ which offers a 64-lead package. Verify that any substitute maintains the 48-lead LQFP form factor and I2C interface compatibility.
