AD9927BBCZ

Overview

The AD9927BBCZ is a 14-bit CCD signal processor featuring an integrated analog front end and timing generator. It includes an 18-channel vertical driver, a Precision Timing core with approximately 400 ps resolution at 40 MHz operation, and a complete set of horizontal clocks. The analog front end comprises a correlated double sampler (CDS), a variable gain amplifier (VGA) with 6 dB to 42 dB range, black level clamp, and a 14-bit ADC. The device operates on 1.8 V for the AFE core and supports 3 V or 1.8 V systems. It is housed in a 128-lead CSP_BGA package measuring 9 mm × 9 mm.

Feature Summary

• Integrated 18-channel vertical driver supporting up to 24 programmable vertical clock signals for advanced CCD control.
• Complete analog front end including CDS, VGA, black level clamp, and 14-bit ADC for high-fidelity signal processing.
• Precision Timing core providing fine edge resolution for high-speed clocks and full-function programmable timing generation.
• On-chip charge pump and LDO regulator enabling compatibility with both 3 V and 1.8 V system architectures.

Applications

• Digital still cameras

Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm RoHS compliance and lead-free status as specified in the ordering guide. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the CMOS circuitry.

Selection Notes

Select this component for applications requiring a highly integrated solution for CCD signal processing. Ensure the design accommodates the specific voltage requirements for the AFE core (1.8 V) and the various driver supplies (up to 3.3 V). Verify that the 128-lead CSP_BGA package fits within the available PCB area and thermal constraints.
