AD9949KCPRL

Overview

The AD9949KCPRL is a 12-bit CCD signal processor featuring a complete analog front end and programmable timing driver. It supports pixel rates up to 36 MHz with a 36 MSPS ADC. The device includes a correlated double sampler, 0 dB to 18 dB PxGA, and 6 dB to 42 dB VGA. A Precision Timing core provides clock adjustment with less than 600 ps resolution. It operates on 2.7 V to 3.6 V supplies within a -20°C to +85°C temperature range. Configuration is managed via a 3-wire serial interface.

Feature Summary

• Integrates a 12-bit ADC with correlated double sampling and variable gain amplification for high-fidelity signal processing.
• Features a Precision Timing core enabling sub-600 ps resolution for precise control of high-speed CCD clocks.
• Includes on-chip drivers capable of directly powering RG and H1-H4 horizontal outputs at 3 V levels.

Applications

• Digital still cameras
• High speed digital imaging applications

Procurement Notes

Verify the specific suffix KCPRL against the manufacturer's current ordering guide to confirm package type and reel specifications. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the component matches the required RoHS compliance and lead-free standards for your assembly process before finalizing orders.

Selection Notes

Select this component when designing systems requiring integrated CCD signal conditioning and timing generation in a single chip. Verify that the maximum 36 MHz pixel rate aligns with the target sensor specifications. Ensure the 40-lead LFCSP package footprint fits the PCB layout constraints and thermal requirements are met given the 320 mW power dissipation at full operation.

Part Context

The AD9949 belongs to Analog Devices' family of CCD signal processors designed for digital imaging. It consolidates analog front-end functions and timing drivers to simplify system architecture. This integration reduces board space and component count compared to discrete solutions, making it suitable for compact consumer electronics and specialized imaging devices.

Replacement Considerations

The AD9949A is a variant supporting line lengths greater than 4096 pixels due to different H-counter behavior. Check the datasheet ordering guide for other pin-compatible alternatives if supply is restricted.
