AD9923ABBCZRL

Overview

The AD9923ABBCZRL is a CCD signal processor featuring an integrated analog front end, timing generator, and 15-channel vertical driver. It includes a 12-bit ADC operating at 36 MHz, a variable gain amplifier (VGA) with 6 dB to 42 dB range, and a correlated double sampler (CDS). The device supports 5-field, 10-phase vertical clocks and offers Precision Timing core adjustment with approximately 600 ps resolution. Power supplies include AVDD, TCVDD, RGVDD, HVDD, DRVDD, DVDD, VDD1/2, VH1/2, VL1/2, VM1/2, VLL, and VMM. Operating temperature ranges from -25°C to +85°C.

Feature Summary

• Integrated 15-channel vertical driver supporting up to 10-phase CCDs
• On-chip timing generator with Precision Timing core for high-speed clock adjustment
• Analog front end comprising CDS, VGA, black level clamp, and 12-bit ADC
• Programmable horizontal drivers for RG, HL, H1 to H4 outputs

Applications

• Digital still cameras
• CCD imaging applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Request original datasheets and material safety data sheets prior to acquisition. Confirm package integrity and moisture sensitivity levels upon receipt. Ensure supply chain documentation matches the specific AD9923ABBCZRL designation.

Selection Notes

Select this component for systems requiring integrated CCD control and signal processing. Verify compatibility with 5-field, 10-phase CCD architectures. Ensure power supply rails match specified voltage ranges for AFE, digital, and vertical driver sections. Confirm interface requirements align with the 3-wire serial programming protocol.

Part Context

The AD9923A belongs to the AD9923 family of CCD signal processors. This revision provides enhanced timing precision compared to earlier versions. The device consolidates analog front-end processing and timing generation into a single package, reducing external component count for camera designs.

Replacement Considerations

The AD9923BBCZRL serves as a functional predecessor within the same product family. Verify register map compatibility and timing specifications when transitioning between revisions.
