AD9923ABBCZ

Overview

The AD9923ABBCZ is a CCD signal processor designed for digital still cameras and imaging systems. It integrates a 15-channel vertical driver, a fully programmable timing generator with Precision Timing core (<600 ps resolution), and an analog front end featuring a 12-bit, 36 MHz ADC. The AFE includes correlated double sampling (CDS), a 6 dB to 42 dB variable gain amplifier (VGA), and black level clamping. Operating on 2.7 V to 3.6 V supplies, it supports 5-field, 10-phase vertical clocks and electronic/mechanical shutter control via a 3-wire serial interface. The device is housed in an 8 mm × 8 mm CSP_BGA package.

Feature Summary

• Integrates a 15-channel vertical driver supporting up to 15 channels for 5-field, 10-phase CCDs.
• Includes a complete on-chip timing generator providing all necessary CCD clocks including RG, H-clocks, and vertical clocks.
• Features a Precision Timing core allowing high-speed clock adjustment with approximately 600 ps resolution at 36 MHz operation.
• Analog front end comprises black level clamping, CDS, VGA, and a 12-bit ADC.

Applications

• Digital still cameras
• CCD imaging applications

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and temperature range. Confirm current availability status as product lifecycle changes may affect supply. Ensure compatibility with system voltage requirements of 2.7 V to 3.6 V before integration.

Selection Notes

Select this component for designs requiring integrated CCD timing generation and analog front-end processing. Verify that the 15-channel V-driver capacity meets the target CCD's vertical transfer requirements. Ensure the system can accommodate the 8 mm × 8 mm CSP_BGA footprint and thermal dissipation characteristics specified in the datasheet.

Part Context

The AD9923A is part of Analog Devices' CCD signal processor family, offering a complete 36 MHz front-end solution. It shares similar register mapping with the AD9923, facilitating software portability. The device consolidates timing generation, vertical driving, and analog-to-digital conversion into a single compact package for image sensor interfaces.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers or updated revisions. Do not assume functional equivalence with other models without verifying pinout, register maps, and electrical specifications against the manufacturer's guidelines.
