AD9991KCPZRL

Overview

The AD9991KCPZRL is a 10-bit CCD signal processor featuring an integrated analog front end and a Precision Timing generator. It supports pixel rates up to 27 MHz with a 10-bit A/D converter, Correlated Double Sampler (CDS), and a Variable Gain Amplifier (VGA) offering 6 dB to 42 dB gain range. The device includes on-chip drivers for RG and H-clocks, black level clamping, and electronic/mechanical shutter control. It operates on multiple 2.7 V to 3.6 V supplies and is housed in a 56-lead LFCSP package.

Feature Summary

• Integrates a complete analog front end with CDS, VGA, and 10-bit ADC
• Features a Precision Timing core with 800 ps resolution for high-speed clock generation
• Includes on-chip 3 V horizontal and reset gate drivers for direct CCD connection
• Supports 2-phase and 4-phase H-clock modes with programmable vertical timing

Applications

• Digital still cameras
• Digital video camcorders
• Industrial imaging systems

Procurement Notes

Verify the specific ordering suffix KCPZRL against the manufacturer's current documentation to confirm package type and reel configuration. Ensure compatibility with system voltage requirements and serial interface protocols before integration. Check for any recent product change notices or lifecycle status updates directly from Analog Devices.

Selection Notes

Select this component when a highly integrated solution for CCD signal processing is required. It is suitable for applications needing precise timing control and onboard driver capabilities. Consider the 56-lead LFCSP footprint and operating temperature range of -20°C to +85°C during design.

Part Context

The AD9991KCPZRL belongs to the AD9991 family of CCD signal processors from Analog Devices. It is designed to replace discrete analog front-end solutions by integrating amplification, conversion, and timing generation into a single chip, simplifying PCB layout and reducing component count in imaging systems.
