AD9948KCPZRL

Overview

The AD9948KCPZRL is a 10-bit CCD signal processor featuring an integrated analog front end and Precision Timing core. It supports pixel rates up to 25 MHz with a 3-wire serial interface for configuration. The device includes a Correlated Double Sampler, Pixel Gain Amplifier (0 dB to 18 dB), Variable Gain Amplifier (6 dB to 42 dB), and black level clamp. Power supplies range from 2.7 V to 3.6 V across AVDD, HVDD, RGVDD, DRVDD, and DVDD. Operating temperature spans -20°C to +85°C in a 40-lead LFCSP package.

Feature Summary

• Integrates a complete analog front end with a 10-bit A/D converter and programmable timing driver.
• Features a Precision Timing core allowing high-speed clock adjustment with 800 ps resolution.
• Includes on-chip drivers for Reset Gate and four horizontal CCD clocks.

Applications

• Digital still cameras
• High speed digital imaging applications

Procurement Notes

Verify the specific ordering suffix KCPZRL against the manufacturer's current documentation to confirm lead-free status and reel packaging specifications. Ensure compatibility with the required operating temperature range of -20°C to +85°C before finalizing component selection.

Selection Notes

Select this component when a highly integrated solution for CCD signal processing is required. The built-in PxGA and VGA provide flexible gain control, while the Precision Timing core simplifies system design by generating necessary high-speed clocks directly from the master input.

Part Context

This part belongs to the Analog Devices AD9948 family of CCD signal processors. It is designed as a space-saving alternative to discrete solutions, consolidating analog conditioning and timing generation into a single 40-lead LFCSP package for compact camera module designs.

Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic replacements may lack the specific Precision Timing core architecture or integrated H-driver capabilities required for direct pin-to-pin functionality.
