ADV7182AWBCPZ

Overview

The ADV7182AWBCPZ is a 10-bit SDTV video decoder with differential inputs, converting analog baseband signals to YCbCr 4:2:2 data. It features one 10-bit ADC with 4× oversampling and four analog input channels. The device supports NTSC, PAL, and SECAM standards via CVBS, S-Video, and YPrPb formats. It operates on a single 1.8 V supply (AVDD, DVDD, PVDD) ranging from 1.71 V to 1.89 V, with a digital I/O supply (DVDDIO) of 1.62 V to 3.63 V. It provides an 8-bit ITU-R BT.656 output and uses an I²C interface for control.

Feature Summary

• Supports worldwide NTSC, PAL, and SECAM color demodulation with automatic standard detection.
• Features a single 10-bit ADC with 4× oversampling per channel for composite, S-Video, and component modes.
• Includes integrated adaptive comb filters, CTI/DNR enhancement, and Adaptive Contrast Enhancement (ACE).
• Provides full Vertical Blank Interval (VBI) data slicing with teletext support and Rovi copy protection detection.

Applications

• Advanced driver assistance systems
• Automotive infotainment units
• Digital video recorders for security surveillance

Procurement Notes

Verify the specific suffix 'W' against official documentation to confirm if it denotes automotive qualification or temperature range variations. Ensure the LFCSP-32 package matches the required PCB footprint. Confirm RoHS compliance status and lead-free specifications prior to ordering.

Selection Notes

Select this component when differential or single-ended analog video inputs are required without external amplifiers. It is suitable for applications needing robust VBI data extraction and copy protection handling. Consider the 1.8 V power supply requirements and I²C control interface compatibility with the host processor.
