AD9923BBCZ

Overview

The AD9923BBCZ is a complete CCD signal processor designed for digital still cameras and imaging applications. It integrates a 12-bit, 36 MHz analog-to-digital converter (ADC), a fully programmable timing generator, and a 15-channel vertical driver. The device features a Precision Timing core with approximately 600 ps resolution at 36 MHz operation. Key internal blocks include a correlated double sampler (CDS), a variable gain amplifier (VGA) with 6 dB to 42 dB range, and a black level clamp. It supports 5-field, 10-phase vertical clock modes and includes on-chip drivers for external crystals and horizontal clocks.

Feature Summary

• Integrates a 12-bit ADC with 36 MHz sampling rate for high-speed image data conversion

• Features a 15-channel vertical driver supporting 5-field, 10-phase vertical clock configurations
• Contains a correlated double sampler and variable gain amplifier for signal conditioning

Applications

• Digital still cameras
• CCD imaging systems
• Front-end solutions for digital photography

Part Context

The AD9923BBCZ belongs to the AD9923 family of CCD signal processors from Analog Devices. It serves as a front-end solution for converting CCD sensor outputs into digital data. The BBCZ suffix typically denotes a specific package variant, often associated with the 8 mm x 8 mm CSP_BGA package with 0.65 mm pitch mentioned in related datasheets for this series.

Replacement Considerations

The AD9923ABBCZRL is a documented similar part within the same family, featuring an 'A' revision status. Designers should verify register map compatibility and timing generator specifications when substituting between these variants.
