AD9992BBCZ

Overview

The AD9992 is a highly integrated CCD signal processor designed for digital still camera applications. It features a complete analog front end with a 12-bit, 40 MHz ADC, Correlated Double Sampler (CDS), and a Variable Gain Amplifier (VGA) offering 6 dB to 42 dB gain. The device includes a Precision Timing core with 400 ps resolution for generating up to 24 vertical clock outputs and horizontal drivers. It operates on a 1.8 V AFE core with internal LDO regulation and supports 3 V or 1.8 V systems. The component is housed in a 105-lead CSP_BGA package measuring 8 mm × 8 mm with a 0.65 mm pitch.

Feature Summary

• Integrates a 12-bit ADC with CDS and VGA for high-fidelity signal processing
• Features a Precision Timing core with sub-nanosecond resolution for precise CCD control
• Includes on-chip drivers for RG, HL, and H1-H8 clocks to reduce external component count
• Supports master and slave modes via programmable serial interface

Applications

• Digital still cameras
• High-speed digital imaging applications

Procurement Notes

Verify the specific revision status of the AD9992BBCZ part number against current Analog Devices documentation. Confirm that the BBCZ suffix corresponds to the standard lead-free CSP_BGA packaging details provided in the official datasheet. Ensure compatibility with system voltage requirements before procurement.

Selection Notes

Select this component when designing systems requiring a fully integrated CCD signal chain with precise timing generation. Evaluate the 105-lead CSP_BGA footprint constraints and ensure the PCB layout supports the thermal resistance characteristics specified for the package type. Verify that the 40 MHz maximum clock rate meets the target pixel frequency requirements.

Part Context

The AD9992 belongs to the Analog Devices CCD signal processor family, which also includes variants like the AD9991 and AD9992BBCZRL. These devices share similar functional architectures but may differ in pinout, package type, or specific timing capabilities. The AD9992 specifically targets applications needing robust on-chip timing generation alongside analog front-end processing.

Replacement Considerations

The AD9992BBCZRL is a reel-packaged variant of the same functional device. Other family members include the AD9991 and AD9949, though these have different bit resolutions or package types. Direct substitution requires verifying pin compatibility and timing specifications.
