AD9937BCPZRL-27

Overview

The AD9937BCPZRL-27 is a highly integrated CCD signal processor from Analog Devices, packaged in a 56-lead LFCSP. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an operating temperature range of –25°C to +85°C. The device features a 10-bit A/D converter with no missing codes guaranteed, a variable gain amplifier (VGA) offering 6 dB to 40 dB gain, and a correlated double sampler (CDS). It includes a complete on-chip timing generator with a Precision Timing core providing 1.7 ns resolution at 12 MHz operation.

Feature Summary

• Integrates a complete analog front end with black level clamping, CDS, VGA, and a 10-bit A/D converter for high-quality signal processing.
• Features a Precision Timing core that allows adjustment of high-speed clocks with 1.7 ns resolution at 12 MHz operation.
• Provides all necessary CCD clocks including RS, H-clocks, V-clocks, sensor gate pulses, and substrate charge reset pulses.
• Operates via a 3-wire serial interface for programming system registers and control functions.

Applications

• Digital Still Cameras
• Industrial Imaging

Procurement Notes

Verify the specific suffix -27 against official documentation to confirm package option or revision details. Confirm availability status as distribution channels may list limited stock or restricted supply conditions. Ensure compatibility with required operating temperatures and voltage ranges before integration into final designs.

Selection Notes

Select this component when a fully integrated CCD signal processor is required. It combines analog front-end processing with programmable timing generation in a single chip. Consider its 10-bit resolution and 12 MHz maximum clock rate for applications requiring precise CCD control without external timing circuits.

Part Context

The AD9937 belongs to the Precision Timing family of CCD signal processors. It is designed to simplify the design of imaging systems by integrating signal conditioning and timing generation. The BCPZ suffix indicates a Lead Frame Chip Scale Package (LFCSP), while RL typically denotes reel packaging for surface-mount assembly.

Replacement Considerations

Check for AD9937KCP or AD9937KCPRL as potential pin-compatible alternatives within the same series. Verify if the -27 suffix corresponds to a specific package variant or revision not covered by standard ordering guides.
