AD9927BBCZRL

Overview

The AD9927BBCZRL is a highly integrated CCD signal processor manufactured by Analog Devices Inc. It features a 14-bit, 40 MHz analog-to-digital converter (ADC) and an integrated 18-channel vertical driver (V-driver). The device supports a maximum clock rate of 40 MHz with a Precision Timing core providing approximately 400 ps resolution. Operating temperatures range from -25°C to +85°C. Power supply inputs include AVDD, TCVDD, DVDD, and various driver supplies ranging from 1.6 V to 3.6 V. The component 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 comprising correlated double sampler, variable gain amplifier, black level clamp, and 14-bit ADC.
• On-chip precision timing generator capable of adjusting high-speed clocks with fine resolution at 40 MHz operation.
• Internal low-dropout regulator and charge pump circuitry enabling compatibility with both 3 V and 1.8 V systems.

Applications

• Digital still cameras

Procurement Notes

Verify the specific suffix BBCZRL against official documentation to confirm package type and reel configuration. Confirm current availability status as distribution channels may list limited stock or obsolete status. Ensure compliance with RoHS directives and moisture sensitivity levels prior to assembly planning.

Selection Notes

Select this component for applications requiring a fully integrated CCD signal processing solution with on-chip timing generation. Verify that the system requires a 14-bit resolution and supports the specified operating temperature range. Ensure the design accommodates the 128-lead CSP_BGA footprint and necessary power supply rails for the vertical drivers.

Part Context

The AD9927 belongs to the AD9928 family of CCD signal processors. While functionally similar, the AD9927 is specifically optimized for digital still camera applications with distinct vertical driver configurations compared to other variants in the series.
