ADV7180BCPZ

Overview

The ADV7180BCPZ is a 10-bit, 4× oversampling SDTV video decoder in a 40-lead LFCSP package. It supports NTSC, PAL, and SECAM standards with composite, S-Video, and component inputs. The device features three analog channels, an integrated AGC, and Macrovision detection. It outputs 8-bit ITU-R BT.656 data via I2C control. Operating voltage ranges from 1.65 V to 3.6 V across digital and analog supplies. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports worldwide NTSC, PAL, and SECAM color demodulation with automatic standard detection.
• Integrates a single 10-bit ADC with adaptive comb filters for superior chrominance and luminance separation.
• Includes Mini-TBC functionality using ADLLT to track varying video line lengths from sources like VCRs.
• Features a full-featured VBI data slicer supporting teletext, closed captioning, and Macrovision copy protection.

Applications

• Digital camcorders and PDAs
• Low cost SDTV PIP decoders for digital TVs
• Multichannel DVRs for video security
• AV receivers and video transcoding
• PCI-/USB-based video capture and TV tuner cards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current selection guide to confirm package type and temperature grade. Ensure the procurement channel provides valid RoHS compliance documentation. Confirm that the received components match the 40-lead LFCSP physical dimensions specified in the datasheet outline drawings. Check for moisture sensitivity labeling as the device is humidity sensitive.

Selection Notes

Select this part when a compact 40-lead solution is required for industrial or automotive environments operating between -40°C and +85°C. It is suitable for designs needing glueless connection to MPEG encoders or mobile video processors. Consider alternative packages if higher pin counts for 16-bit output or different thermal characteristics are necessary for the specific PCB layout constraints.

Part Context

This component belongs to the ADV7180 series of multiformat video decoders. It shares functional similarities with the ADV7181C but offers distinct package options including 32-lead, 40-lead, 48-lead, and 64-lead variants. The series is designed for space-constrained portable applications and digital television systems requiring high-quality analog-to-digital conversion of standard definition video signals.

Replacement Considerations

The ADV7180KCP32Z serves as a commercial grade alternative in a 32-lead package. For automotive applications requiring extended temperature ranges up to +125°C, the ADV7180WBCPZ is the qualified substitute. Designers should verify pin compatibility and register settings when migrating between these variants.

FAQ

How does the ADV7180BCPZ handle video input signal variations?

It utilizes an integrated AGC with adaptive peak white mode and clamp-restore circuitry to manage input video signal peak-to-peak ranges up to 1.0 V, ensuring consistent digitization across varying source qualities.

What interface is used for configuring the ADV7180BCPZ?

Configuration is performed via a 2-wire serial MPU interface that is I2C compatible, allowing control over registers for input selection, video standards, and power management.
