AD9978AXCPZ

Overview

The AD9978AXCPZ is a dual-channel CCD signal processor manufactured by Analog Devices Inc. It integrates two complete analog front ends with 14-bit, 65 MHz analog-to-digital converters for high-speed digital video applications. The device features a Precision Timing core allowing correlated double sampler and sample-and-hold amplifier clock adjustment with 240 ps resolution at 65 MHz operation. It supports differential analog inputs, variable gain amplifiers ranging from 6 dB to 42 dB, and black level clamp with variable level control. The unit operates on a 1.8 V analog and digital core supply voltage and includes reduced range LVDS outputs for serial data transmission.
