AD9925BBCZRL

Overview

The AD9925BBCZRL is a CCD signal processor featuring an integrated analog front end and timing generator. It includes a 10-channel vertical driver supporting up to +15 V and −8 V levels, and a Precision Timing core with <600 ps resolution at 36 MHz operation. The analog section comprises a correlated double sampler, a 6 dB to 42 dB variable gain amplifier, and a 12-bit ADC. Power supplies range from 2.7 V to 3.6 V for logic and analog sections, while the V-driver utilizes VH (10.5 V to 16.0 V), VM (−1.0 V to +3.0 V), and VL (−10.0 V to −6.0 V). The device operates between −25°C and +85°C in a 9x9 mm CSPBGA package.

Feature Summary

• Integrated 10-channel vertical driver with support for advanced CCD voltage levels
• Complete on-chip timing generator with high-resolution programmable edge control
• Analog front end including black level clamp, CDS, VGA, and 12-bit ADC

Applications

• Digital still cameras
• Digital video camcorders
• CCD camera modules

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific revision markings corresponding to Rev A documentation. Ensure proper ESD handling protocols are followed during storage and assembly due to the sensitivity of the CMOS structure.

Selection Notes

Select this component when designing systems requiring a complete CCD interface solution with integrated timing generation. Ensure the target CCD sensor supports the required vertical clock configurations and voltage ranges provided by the internal drivers. Verify that the system microprocessor can accommodate the 3-wire serial interface for register programming and timing configuration.

Part Context

This part belongs to the AD9925 family of CCD signal processors. It is based on the AD9995 product architecture but adds a dedicated 10-channel vertical driver. The BBCZRL suffix indicates a specific reel packaging format within the broader AD9925 series designed for digital imaging applications.

Replacement Considerations

The AD9928 is a related dual-channel processor but differs in channel count and integration. Direct pin-to-pin replacement requires verification of register compatibility and timing generator specifications against the original design requirements.
