ADDI7018BCPZ

Overview

The ADDI7018BCPZ is a dual-channel, 16-bit high-definition image signal processor designed for CCD signal processing in digital video cameras. It integrates two complete analog front ends (AFE) with ADC conversion, supporting pixel rates up to 75 MHz. The device features a Precision Timing core providing 210 ps resolution at 75 MHz operation. Each channel includes black level clamping, correlated double sampling (CDS), and a variable gain amplifier (VGA) with 6 dB to 42 dB range. It utilizes reduced range LVDS outputs and operates on a 1.8 V supply within an operating temperature range of −25°C to +85°C.

Feature Summary

• Dual-channel architecture with integrated analog front ends and 16-bit ADCs
• Precision Timing core enabling precise clock adjustment for CDS and SHA
• Configurable VGA offering variable gain control from 6 dB to 42 dB
• Reduced range LVDS interface for serial data output

Applications

• HD broadcast cameras
• High speed industrial cameras
• Professional digital cameras
• Digital copiers

Procurement Notes

Verify the specific suffix BCPZ against the manufacturer's official documentation to confirm package type and temperature rating. Confirm current availability status as distribution channels may list obsolete or discontinued variants. Ensure compatibility with system voltage requirements and interface standards before procurement.

Selection Notes

Select this component for applications requiring dual-channel CCD processing with high timing precision. Evaluate the need for 75 MHz pixel rate support and 16-bit resolution. Consider the 1.8 V power supply constraint and the space-saving 40-lead LFCSP package dimensions for PCB layout integration.

Part Context

The ADDI7018 belongs to Analog Devices' Precision Timing family of image signal processors. It serves as a specialized solution for high-speed digital video capture systems. The device replaces older discrete solutions by integrating AFE functions into a single compact package, simplifying design complexity for professional imaging equipment manufacturers.

Replacement Considerations

The datasheet notes pin-compatibility with the AD9978A. Verify functional equivalence and parameter alignment before substitution. Consult official documentation for any differences in timing specifications or interface configurations.
