Product Overview
The ADV7184BSTZ is a multi-format SDTV video decoder from Analog Devices. It integrates four high-speed 10-bit ADCs and an adaptive 3D comb filter to detect and convert NTSC, PAL, SECAM analog CVBS, S-Video and YPrPb signals into ITU-R BT.656 / BT.601 digital video. Equipped with optimized sync and chroma processing for noisy input signals, this 80-LQFP industrial-grade chip (-40°C ~ +85°C) suits automotive display, video capture, surveillance DVR and analog video conversion equipment.
Core Advantages
Multi-Standard Automatic Video Decoding
Auto identifies NTSC, PAL, SECAM formats for CVBS, S-Video and component inputs without MCU control.
3D Adaptive Comb Filter
Separates luminance and chroma signals effectively, eliminating cross-color interference and improving image quality.
High Precision Analog Sampling
Four integrated 10-bit 54MHz ADCs with oversampling maintain detail under low-light and high-noise conditions.
Compatible Standard Digital Interface
Supports 8/16-bit 4:2:2 YCrCb output conforming to BT.656/BT.601, easy to connect with FPGA and video processors.

Frequently Asked Questions
Q1: What does the “Z” in ADV7184BSTZ stand for?
A: The “Z” suffix means lead-free and RoHS-compliant packaging complying with global environmental regulations.
Q2: Can ADV7184BSTZ process poor or unstable analog video signals?
A: Yes. Built-in AGC, adaptive line clamping and sync processing stabilize jittery signals from VCR tapes and long transmission cables.
Q3: Which interface controls the ADV7184BSTZ?
A: Configuration and status monitoring are implemented via standard 2-wire I²C serial interface.
Q4: What power rails are required for ADV7184BSTZ hardware design?
A: Dual power supply: 1.8V for digital core, 3.3V for analog front-end and digital I/O buffers.
Q5: What crystal frequency should be matched with this chip?
A: A 28.63636 MHz crystal oscillator is required for normal operation.
Q6: How many analog video input channels does ADV7184BSTZ support?
A: It supports up to 12 analog video input channels for flexible multi-channel video acquisition.
Q7: Is ADV7184BSTZ suitable for automotive projects?
A: Yes. Industrial temperature range (-40°C ~ +85°C) supports automotive display and camera video conversion systems.
Q8: Are there alternative or pin-to-pin compatible models for ADV7184BSTZ?
A: ADV7180 and ADV7181D are common alternative video decoders. They share similar functions but feature fewer input channels. There is no fully pin-compatible replacement; hardware circuit adjustment is needed if switching models. Contact us for component substitution suggestions.
