AD14060BF-4

Overview

The AD14060BF-4 is a Quad-SHARC DSP multiprocessor module integrating four ADSP-21060 cores within a single hermetic package. It delivers 480 MFLOPS peak performance with a 25 ns instruction rate and includes 16 Mbits of shared on-module SRAM. The device supports both 5 V and 3.3 V operation, featuring twelve 40 MB/s link ports, independent serial ports, and a common serial port. It utilizes a 308-lead ceramic quad flatpack (CQFP) with a 0.160-inch low profile and 25 mil lead pitch for high-density applications.

Feature Summary

• Integrates four ADSP-21060 SHARC cores providing 480 MFLOPS peak performance
• Includes 16 Mbits of internal shared SRAM accessible via a 48-bit data bus
• Features twelve 40 MB/s link ports and multiple serial communication interfaces
• Hermetic 308-lead CQFP package supporting 5 V and 3.3 V supply voltages

Applications

• High-performance digital signal processing systems requiring parallel execution
• Multiprocessor architectures utilizing shared memory and direct core-to-core communication
• Complex real-time signal processing tasks in aerospace or defense environments

Procurement Notes

Verify the specific grade (B or K) and voltage compatibility (5 V vs. 3.3 V) required for the target application before procurement. Confirm that the host system supports the 308-lead CQFP form factor and hermetic packaging requirements. Ensure that the development environment includes appropriate tools for the ADSP-21060 architecture, such as JTAG emulators and compiler suites compatible with the Quad-SHARC configuration.

Selection Notes

Select the AD14060BF-4 when a single-package solution for four SHARC processors is needed to minimize board space and interconnect complexity. Choose this component over discrete ADSP-21060 chips if the design requires integrated shared SRAM and pre-routed link ports. Consider the B Grade (-40°C to +100°C) or K Grade (0°C to +85°C) based on the specific case operating temperature constraints of the final assembly.

Part Context

The AD14060/AD14060L represents the first generation of high-performance DSP multiprocessor modules from Analog Devices. Built around the ADSP-21060 core, it was designed to offer the highest performance-to-density ratio in its class. This module simplifies the implementation of complex multiprocessor systems by embedding power planes, matched impedance interconnects, and optimized signal routing directly within the package.

Replacement Considerations

The AD14160 is a similar Quad-SHARC module available in a different package format. For discrete replacements, individual ADSP-21060 processors can be used, but this requires external implementation of the shared bus, SRAM, and link port interconnections, significantly increasing board complexity.
