ADV7180KST48Z-RL

Overview

The ADV7180KST48Z-RL 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 an integrated AGC, adaptive comb filters, and Mini-TBC functionality via ADLLT. It outputs 8-bit ITU-R BT.656 data and operates on a single 1.8 V supply with I2C control.

Feature Summary

• Supports worldwide NTSC, PAL, and SECAM color demodulation with automatic standard detection.
• Includes three analog video input channels with on-chip antialiasing filters and integrated AGC.
• Provides 5-line adaptive comb filters and CTI/DNR video enhancement for improved signal quality.
• Features Mini-TBC capability through adaptive digital line length tracking and enhanced FIFO management.

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 suffix KST48Z against the manufacturer's current ordering guide to confirm package type and temperature grade. Ensure the reel packaging matches production requirements. Confirm RoHS compliance status as per the latest datasheet revision. Check for any automotive qualification markings if required for the application environment.

Selection Notes

Select this component when a compact 48-lead LQFP package is required for space-constrained designs. It offers pin compatibility with other variants in the ADV7180 family but provides specific thermal and electrical characteristics for industrial or commercial use. Consider the 1.8 V supply requirement and I2C interface compatibility with the host processor.

Part Context

This part belongs to the ADV7180 series of single-chip multiformat video decoders. It shares core decoding capabilities with other packages like the 32-lead LFCSP and 64-lead LQFP but differs in physical footprint and pin count. The 48-lead LQFP variant balances channel availability and board space efficiency.

Replacement Considerations

The ADV7180WBST48Z is a qualified automotive version with extended temperature range. The ADV7180BSTZ is the commercial 64-lead LQFP equivalent with additional channels. Verify pinout compatibility and thermal performance before substitution.

FAQ

Does the ADV7180KST48Z support S-Video inputs?

Yes, the device supports CVBS (composite), Y/C (S-Video), and YPrPb (component) video input formats.

What is the output format of the ADV7180?

It outputs 8-bit ITU-R BT.656 YCrCb 4:2:2 component video data along with HS, VS, and FIELD synchronization signals.
