AD9991KCP

Overview

The AD9991KCP is a 10-bit CCD signal processor featuring a Precision Timing generator, packaged in a 56-lead LFCSP. It supports pixel rates up to 27 MHz with an operating temperature range of –20°C to +85°C. The analog front end includes a Correlated Double Sampler (CDS), a Variable Gain Amplifier (VGA) with 6 dB to 42 dB gain range, and a Black Level Clamp. Key specifications include a 10-bit A/D converter, 800 ps timing resolution, and on-chip 3 V Horizontal and RG drivers. Power supply voltages for AVDD, TCVDD, RGVDD, HVDD, DRVDD, and DVDD range from 2.7 V to 3.6 V.

Feature Summary

• Integrated analog front end with CDS, VGA, and black level clamp
• Complete on-chip timing generator supporting 2-phase and 4-phase H-clock modes
• Precision Timing core with 800 ps resolution for high-speed clock adjustment
• On-chip drivers for external crystal, horizontal clocks, and reset gate

Applications

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

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official Analog Devices documentation. Ensure the package type matches the specified 56-lead LFCSP form factor. Confirm that the device meets the required environmental specifications for the intended operating temperature range.

Selection Notes

Select this model when a highly integrated CCD signal processor is required for consumer imaging applications. It is suitable for designs needing on-chip timing generation and direct drive capabilities for horizontal and reset gate clocks without external buffer components.

Part Context

This component belongs to the AD9991 series of CCD signal processors manufactured by Analog Devices. It is designed to replace discrete analog front-end solutions by integrating signal conditioning, conversion, and timing generation into a single chip for space-constrained imaging modules.

Replacement Considerations

The AD9991KCPZRL is a reel-packaged variant of the same functional device. Verify pin compatibility and electrical specifications before substituting.
