AD9937KCP

Overview

The AD9937KCP is a highly integrated CCD signal processor from Analog Devices, designed for digital imaging applications. It features a complete analog front end including a 12 MSPS Correlated Double Sampler (CDS), a variable gain amplifier (VGA) with 6 dB to 40 dB range, black level clamp, and a 10-bit A/D converter. The device incorporates a Precision Timing Generator with 1.7 ns resolution for high-speed clock adjustment. It operates on supply voltages between 2.7 V and 3.6 V across an operating temperature range of –25°C to +85°C.

Feature Summary

• Integrates a 10-bit A/D converter with guaranteed no missing codes and a programmable VGA for signal conditioning.
• Includes a Precision Timing core capable of adjusting high-speed clocks with 1.7 ns resolution at 12 MHz operation.
• Provides complete on-chip timing generation for CCD sensors, including horizontal drivers, vertical transfer clocks, and shutter modes.

Applications

• Digital Still Cameras
• Industrial Imaging

Procurement Notes

Verify the specific suffix KCP indicates the Lead Frame Chip Scale Package (LFCSP-56). Confirm the operating temperature range matches the –25°C to +85°C specification. Ensure compatibility with the required 2.7 V to 3.6 V supply rails. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when a single-chip solution for CCD signal processing is required. It combines analog front-end functions with precise timing control, reducing board space. Consider the 56-lead LFCSP package for compact designs. Verify that the pixel rate requirements do not exceed the specified 12 MHz limit for optimal performance.

Part Context

The AD9937 belongs to Analog Devices' Precision Timing™ family, focusing on specialized signal processing for imaging sensors. This model specifically targets CCD-based systems, offering integrated timing and analog conversion. It serves as a key component in simplifying the design of camera modules by consolidating multiple discrete functions into one IC.

Replacement Considerations

Check for the AD9937KCPRL variant if reel packaging is preferred over cut tape. No direct functional substitutes are listed in the provided datasheet; verify pinout and register compatibility if considering alternative CCD processors.
