AD9920ABBCZ

Overview

The AD9920ABBCZ is a highly integrated charge-coupled device (CCD) signal processor designed for digital still camera applications. It combines a complete analog front end with a full-function programmable timing generator and a 19-channel vertical driver. The analog front end features a 12-bit, 40.5 MHz ADC, correlated double sampler (CDS), and black level clamp. The timing generator supports up to 24 vertical clock signals and includes a Precision Timing core with approximately 400 ps resolution at 40.5 MHz operation. The device operates over a temperature range of −25°C to +85°C.

Feature Summary

• Integrated 19-channel V-driver supporting six-field CCDs
• 12-bit, 40.5 MHz analog-to-digital converter (ADC)
• Correlated double sampler (CDS) with selectable gain: −3 dB, 0 dB, +3 dB, and +6 dB
• Precision Timing core providing ~400 ps resolution at 40.5 MHz
• Complete on-chip timing generator with 24 programmable vertical clock signals

Applications

• Digital still cameras

Procurement Notes

Verify the specific suffix 'BBCZ' against the manufacturer's ordering guide to confirm package type and material specifications. Confirm availability status as distribution data may vary. Ensure compatibility with required supply voltages including AVDD, TCVDD, and DVDD at 1.8 V nominal.

Selection Notes

Select this component for applications requiring high integration of CCD control and signal processing. Ensure the system design accommodates the multiple power supplies (AVDD, TCVDD, HVDD, etc.) and the 105-ball CSP_BGA package. Verify that the CLI frequency requirements fall within the 10 MHz to 40.5 MHz range.

Part Context

The AD9920A is part of Analog Devices' CCD signal processor family. The AD9920ABBCZ specifically denotes the version in a 105-ball, 8 mm × 8 mm CSP_BGA package. It serves as a direct replacement for earlier revisions or variants within the AD9920A series, maintaining functional compatibility while potentially differing in packaging or manufacturing lot details.

Replacement Considerations

Check the manufacturer's ordering guide for pin-compatible alternatives such as the AD9920A BBCZ. Verify that any substitute maintains the same 105-ball CSP_BGA footprint and electrical specifications, particularly the 12-bit ADC performance and V-driver capabilities.
