AD9929BBCZ

Overview

The AD9929BBCZ is a highly integrated CCD signal processor manufactured by Analog Devices Inc. It features a 12-bit A/D converter operating at pixel rates up to 36 MHz, combined with a complete analog front end and a programmable timing generator. The device includes a 36 MSPS correlated double sampler (CDS), a variable gain amplifier (VGA) with 6 dB to 40 dB range, and a black level clamp. On-chip drivers support direct connection to CCD sensors, providing horizontal clocks, vertical transfer clocks, and substrate bias pulses. It operates on multiple power supplies ranging from 2.7 V to 3.6 V for digital/analog sections and higher voltages for vertical drivers. The component is housed in a 64-lead CSPBGA package and functions within an operating temperature range of −25°C to +85°C.

Feature Summary

• Integrates a 12-bit A/D converter with a 36 MSPS correlated double sampler and a variable gain amplifier for precise signal conditioning.
• Includes a complete on-chip timing generator with Precision Timing core for accurate synchronization of CCD sensor operations.
• Features dedicated on-chip horizontal and vertical clock drivers capable of directly interfacing with CCD image sensors.

Applications

• Digital still cameras
• Digital video camcorders

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and environmental rating. Confirm that the intended application environment falls within the specified operating temperature limits. Ensure proper power supply sequencing is implemented during system startup to maintain device reliability and prevent latch-up conditions.

Selection Notes

Select this component when a single-chip solution for CCD signal processing is required. It is suitable for designs needing integrated timing generation and high-speed analog-to-digital conversion. Verify that the target CCD sensor interface matches the available driver outputs and voltage requirements.

Part Context

The AD9929 belongs to the Analog Devices family of CCD signal processors. It consolidates analog front-end processing, digitization, and timing control into a single integrated circuit. This integration reduces board space and simplifies the design of imaging systems compared to discrete component solutions.

Replacement Considerations

Consult official Analog Devices documentation for verified replacement part numbers or updated revisions. Do not substitute with generic CCD processors without verifying pin compatibility and timing specifications.
