AD9937BCPZ-24

Overview

The AD9937BCPZ-24 is a highly integrated CCD signal processor from Analog Devices, packaged in a 56-lead LFCSP. It features a complete analog front end with a 10-bit A/D converter and a full-function programmable timing generator. The device supports pixel rates up to 12 MHz and includes a Precision Timing core with 1.7 ns resolution. Key analog components include a Correlated Double Sampler (CDS), a variable gain amplifier (VGA) offering 6 dB to 40 dB gain, and a black level clamp. It operates on multiple power supplies ranging from 2.7 V to 3.6 V.

Feature Summary

• Integrates a 10-bit A/D converter with guaranteed no missing codes and a 12 MSPS correlated double sampler for high-fidelity signal processing.
• Features a Precision Timing core capable of adjusting high-speed clocks with 1.7 ns resolution at 12 MHz operation.
• Includes an on-chip variable gain amplifier providing 6 dB to 40 dB adjustable gain range with monotonic control.
• Provides complete on-chip timing generation including horizontal drivers, vertical transfer clocks, and sync signals.

Applications

• Digital Still Cameras
• Industrial Imaging

Procurement Notes

Verify the specific suffix '24' against official documentation, as standard listings typically show 'KCP'. Confirm current availability status directly with Analog Devices or authorized distributors, as supply conditions may vary. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS technology.

Selection Notes

Select this component for applications requiring a single-chip solution for CCD signal conditioning and timing. It is suitable where space constraints favor the compact LFCSP package. Consider the 12 MHz maximum clock rate and 10-bit resolution when matching system requirements. Verify compatibility with the target CCD sensor's voltage levels and timing specifications.

Part Context

The AD9937 belongs to Analog Devices' Precision Timing family, designed specifically for CCD signal processing. It consolidates functions that would otherwise require multiple discrete components, simplifying board layout and reducing system complexity. The device is engineered for high performance in imaging systems requiring precise synchronization and low noise.

Replacement Considerations

Check for the AD9937KCP variant which shares the same functional specifications but may differ in packaging or temperature grade. Verify pinout and register compatibility before substitution. No other direct substitutes are documented in the provided source material.
