ADV7182ABCPZ-RL

Overview

The ADV7182ABCPZ-RL is a multiformat SDTV video decoder featuring a single 10-bit ADC with 4× oversampling. It supports NTSC, PAL, and SECAM standards via CVBS, S-Video, and YPrPb inputs. The device outputs 8-bit ITU-R BT.656 YCbCr data through an I²C interface. It operates on a single 1.8 V supply (AVDD, DVDD, PVDD) and a separate 1.62 V to 3.63 V digital I/O supply (DVDDIO). Available in a 32-lead LFCSP package, it includes automotive grade (-40°C to +105°C) and industrial grade (-40°C to +85°C) options.

Feature Summary

• Automatically detects and decodes worldwide NTSC, PAL, and SECAM video standards from composite, S-Video, or component sources.
• Integrates a five-line adaptive comb filter for superior chrominance and luminance separation.
• Features Adaptive Contrast Enhancement (ACE) to improve visibility of objects in shaded areas.
• Includes integrated AGC and Rovi copy protection detection circuitry.

Applications

• Advanced driver assistance systems
• Automotive infotainment units
• Video security DVRs

Procurement Notes

Verify the specific suffix against official documentation to confirm temperature range and packaging type. Ensure the DVDDIO voltage matches the target system logic levels, as it supports a wide range up to 3.63 V. Confirm RoHS compliance status and check for any recent product lifecycle changes or obsolescence notices directly from Analog Devices.

Selection Notes

Select this component when differential or single-ended analog video inputs require direct connection without external amplifiers. It is suitable for designs needing robust handling of noisy video sources like VCRs due to ADLLT tracking. Verify that the required output format aligns with the 8-bit ITU-R BT.656 standard and that the I²C control interface fits the system architecture.

Part Context

This part belongs to the ADV7182A family of video decoders. It shares pinout and software compatibility with the ADV7182. The device is designed to convert standard analog baseband signals into digital component video streams, serving as a bridge between legacy analog video sources and modern digital processing systems.

FAQ

Does the ADV7182A support differential video inputs?

Yes, the analog front end features a differential-to-single-ended converter that accommodates direct connection of fully differential, pseudo-differential, or single-ended CVBS signals.

What is the purpose of the ADLLT algorithm?

Adaptive Digital Line Length Tracking allows the decoder to track and decode poor-quality video sources with varying line lengths, such as those from VCRs or noisy tuner outputs.
