AD9928BBCZRL

Overview

The AD9928BBCZRL is a dual-channel, 14-bit CCD signal processor featuring an integrated timing generator and 18-channel vertical driver. It operates with a 1.8 V analog front-end core and includes internal LDO regulators for 3 V system compatibility. The device incorporates a Precision Timing core providing approximately 390 ps resolution at 40 MHz operation. It supports serial data output via a reduced range LVDS interface and features a 128-ball CSP_BGA package measuring 9 mm × 9 mm with a 0.65 mm pitch.

Feature Summary

• Dual analog front ends with 14-bit ADCs, black level clamping, correlated double sampling, and variable gain amplifiers.
• Programmable timing generator supporting up to 24 vertical clock signals and on-chip horizontal and RG drivers.
• Precision Timing core enabling high-speed clock adjustment with fine resolution.
• Seven general-purpose outputs designed for shutter support and system control functions.

Applications

• High speed digital imaging
• Surveillance cameras
• Industrial cameras

Procurement Notes

Verify the specific suffix BBCZRL against the manufacturer's current datasheet revision to confirm pinout and electrical specifications match your design requirements. Confirm availability status directly with Analog Devices or authorized distributors, as supply constraints may affect lead times. Ensure the 128-ball CSP_BGA package dimensions and thermal characteristics are compatible with your PCB layout and assembly processes before finalizing procurement.

Selection Notes

Select this component when designing systems requiring a highly integrated CCD signal processor with precise timing control. The internal LDO regulators simplify power distribution by allowing direct 3 V operation while maintaining a 1.8 V core. Consider the 14-bit resolution and variable gain amplifier capabilities for applications demanding high dynamic range and low noise performance in digital imaging environments.

Part Context

The AD9928 belongs to Analog Devices' family of CCD signal processors, designed specifically for digital still-image camera applications. It integrates complex analog and digital functions into a single chip, reducing board space and component count. The device shares register compatibility with similar models like the AD9920A and AD9990, facilitating potential migration paths for existing designs requiring enhanced timing precision or additional channel support.

Replacement Considerations

The AD9928BBCZ-60 is a 60 MHz grade variant within the same product family. Verify if the higher clock speed meets application needs without compromising other specifications. No other direct substitutes are documented in the provided source material.
