AD9990BBCZRL

Overview

The AD9990BBCZRL is a dual-channel, 14-bit CCD signal processor and precision timing core manufactured by Analog Devices Inc. It integrates an analog front end with analog-to-digital conversion and a programmable timing generator for two-channel output CCDs. Each channel supports operation up to 32 MHz. The device features a Precision Timing core with approximately 488 ps resolution at 32 MHz operation. It includes internal LDO regulators operating at 1.8 V and on-chip 3 V horizontal and RG drivers. The component is housed in a 112-ball CSP_BGA package measuring 8 mm × 8 mm with a 0.65 mm pitch.

Feature Summary

• Integrates a complete analog front end with correlated double sampling, variable gain amplification, black level clamping, and 14-bit ADCs for each of the two channels.
• Provides a full-function programmable timing generator capable of supporting up to 24 vertical clock signals for advanced CCD control.
• Includes a Precision Timing core allowing high-speed clock adjustment with fine resolution and on-chip drivers for external crystals and synchronization.

Applications

• Digital still cameras

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm current availability status directly with the manufacturer or authorized distributors, as supply conditions may vary. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to handling and storage.

Selection Notes

Select this component for applications requiring integrated CCD signal processing and precise timing generation within a compact footprint. Consider the 1.8 V AFE core voltage and internal LDO regulators when designing power delivery networks. Verify that the 32 MHz per channel speed meets system requirements and that the 112-ball BGA package fits the PCB layout constraints.

Part Context

The AD9990 belongs to Analog Devices' family of CCD signal processors designed for consumer imaging applications. It combines analog signal conditioning with digital timing control to simplify system design for digital still cameras. The BBCZRL suffix indicates a specific reel packaging configuration within the AD9990 product line.

Replacement Considerations

Consult the AD9990 datasheet for officially documented substitute part numbers or pin-compatible alternatives. Verify functional equivalence regarding timing resolution, channel count, and package dimensions before considering any cross-references.
