AD9923BBCZRL

Overview

The AD9923BBCZRL is a CCD signal processor from Analog Devices, designed for digital still cameras and imaging applications. It integrates a 15-channel vertical driver, a 12-bit ADC operating at 36 MHz, and a Precision Timing generator. The device features a correlated double sampler, a variable gain amplifier with 6 dB to 42 dB range, and black level clamp functionality. It supports electronic and mechanical shutter modes and includes on-chip drivers for external crystals and horizontal clocks. The component is housed in an 8 mm × 8 mm CSP_BGA package with a 0.65 mm pitch.

Feature Summary

• Integrates a fully programmable timing generator with a Precision Timing core for high-speed clock adjustment.
• Includes a 15-channel vertical driver and complete analog front-end solution for CCD imaging.
• Features a correlated double sampler and a variable gain amplifier with adjustable gain control.

Applications

• Digital still cameras
• CCD imaging systems

Procurement Notes

Verify the specific suffix 'BBCZRL' against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement. Check for any product change notices or end-of-life announcements that may affect long-term supply availability.

Selection Notes

Select this component when a complete front-end solution for CCD sensors is required. It is suitable for applications needing integrated vertical driving and precise timing generation. Compare its 36 MHz ADC speed and 12-bit resolution against system requirements. Consider the 8x8 mm package size for space-constrained designs.

Part Context

The AD9923BBCZRL belongs to the AD9923 family of CCD signal processors. It shares a similar register map with the standard AD9923 but includes specific revisions or enhancements.
