AD9991KCPZ

Overview

The AD9991KCPZ is a 10-bit CCD signal processor featuring a Precision Timing generator and analog front end. It supports pixel rates up to 27 MHz with a 10-bit A/D converter. The device includes a variable gain amplifier (VGA) with a range of 6 dB to 42 dB, correlated double sampling (CDS), and black level clamping. It provides on-chip drivers for horizontal clocks and reset gate signals. The component operates within a temperature range of -20°C to +85°C and is housed in a 56-lead LFCSP package.

Feature Summary

• Integrated analog front end with 10-bit ADC, VGA, CDS, and black level clamp
• Complete on-chip timing generator supporting 2-phase and 4-phase H-clock modes
• Precision Timing core allowing high-speed clock adjustment with 800 ps resolution
• On-chip output drivers for RG and H1–H4 clocks

Applications

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

Procurement Notes

Verify the specific ordering suffix KCPZ against official Analog Devices documentation to confirm the lead-free status and tape-and-reel or tray packaging configuration. Ensure the component meets RoHS compliance requirements for the intended market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated CCD signal processing with programmable timing generation. Verify that the maximum pixel rate of 27 MHz aligns with the target sensor specifications. Confirm compatibility with the required vertical clocking phases, either 2-phase or 4-mode, and ensure the available serial interface matches the system microprocessor capabilities.

Part Context

The AD9991KCPZ belongs to the AD9991 family of CCD signal processors manufactured by Analog Devices. This series is designed to simplify the interface between CCD sensors and digital image processors by combining analog signal conditioning with precise timing control in a single integrated circuit solution.

Replacement Considerations

The AD9991KCPRL is a verified alternative from the same manufacturer offering identical electrical characteristics and functionality. Both variants utilize the 56-lead LFCSP package and share the same pinout and register map, facilitating direct substitution in existing designs.
