AD9974BBCZ

Overview

The AD9974BBCZ-40 is a dual-channel, 14-bit CCD signal processor featuring a complete analog front end and programmable timing driver. It supports pixel rates up to 65 MHz with a Precision Timing core offering approximately 240 ps resolution. The device integrates a correlated double sampler (CDS) with selectable gains of −3 dB, 0 dB, +3 dB, and +6 dB, alongside a 6 dB to 42 dB variable gain amplifier (VGA). Power supplies include 1.8 V for the analog/digital core and 3.3 V for horizontal and reset gate drivers. It operates within a temperature range of −25°C to +85°C and utilizes a 100-lead, 9 mm × 9 mm CSP_BGA package.

Feature Summary

• Dual-channel architecture with independent analog front ends including black level clamping, CDS, VGA, and ADCs.
• Precision Timing core enables fine adjustment of high-speed clocks with 240 ps resolution at 65 MHz operation.
• Integrated on-chip 3 V horizontal and RG drivers eliminate external buffer requirements.
• Internal low dropout (LDO) regulator circuitry simplifies power distribution.

Applications

• Professional HDTV camcorders
• Professional/high-end digital cameras
• Broadcast cameras
• Industrial high-speed cameras

Procurement Notes

Verify the specific suffix against official documentation to confirm exact electrical or mechanical variants. Confirm package integrity upon receipt as the component uses a fine-pitch BGA format. Ensure ESD precautions are strictly followed during handling due to the sensitivity of the CMOS process technology.

Selection Notes

Select this component when a highly integrated solution for CCD readout is required. The dual-channel design reduces board space compared to single-channel alternatives. Verify that the system master clock frequency aligns with the 65 MHz maximum specification to ensure proper timing generation and data conversion performance.

Part Context

This part belongs to the Analog Devices AD9974 family of CCD signal processors. It serves as a direct upgrade or alternative to earlier generations by providing higher integration levels. The device consolidates functions previously handled by multiple discrete components into a single chip, streamlining the design of high-performance imaging systems.

Replacement Considerations

Check the AD9970 datasheet for single-channel compatibility if only one sensor interface is needed. Review the AD9974 ordering guide for any updated revisions or pin-compatible variants before finalizing the substitution.
