AD9948AKCPZRL

Overview

The AD9948AKCPZRL is a highly integrated CCD signal processor designed for digital still camera applications. It operates at pixel rates up to 36 MHz and integrates a complete analog front end with A/D conversion and a programmable timing driver. The device features a Precision Timing core with less than 600 ps resolution, a Correlated Double Sampler (CDS), a 10-bit Variable Gain Amplifier (VGA) with 6 dB to 42 dB gain range, and a 12-bit, 36 MSPS Analog-to-Digital Converter (ADC). It includes black level clamp functionality, on-chip 3 V horizontal and RG drivers, and supports electronic and mechanical shutter modes within a 40-lead LFCSP package.

Feature Summary

• Integrates a 12-bit ADC and 10-bit VGA for high-fidelity signal processing
• Includes a Precision Timing core for precise clock adjustment
• Features an on-chip Correlated Double Sampler (CDS) for noise reduction

Applications

• Digital still cameras
• High-speed digital imaging applications

Procurement Notes

Verify the specific suffix 'RL' against the manufacturer's official datasheet to confirm reel packaging specifications. Ensure compatibility with the 40-lead LFCSP footprint during procurement planning. Check for current lifecycle status as older model variants may have limited availability or obsolescence notices from Analog Devices.

Selection Notes

Select this component when designing systems requiring a single-chip solution for CCD signal conditioning. The integrated timing generator reduces external component count compared to discrete solutions. Verify that the required pixel rate does not exceed the specified 36 MHz limit and that the supply voltage matches the device requirements.

Part Context

This part belongs to the AD994x family of CCD signal processors from Analog Devices. It shares architectural similarities with the AD9949 but typically offers different gain configurations or feature sets tailored for specific imaging sensor interfaces. It serves as a bridge between analog CCD outputs and digital image processing units.

Replacement Considerations

The AD9949AKCPZRL is a documented alternative within the same product family. Verify pinout compatibility and functional equivalence regarding the ADC resolution and timing core capabilities before substitution.
