AD14060LBF-4

Overview

The AD14060LBF-4 is a Quad-SHARC DSP multiprocessor module based on four ADSP-21060 cores. It delivers 480 MFLOPS peak and 320 MFLOPS sustained performance with a 25 ns instruction rate. The device integrates 16 Mbit of shared SRAM and provides 4 gigawords of addressable off-module memory via a 32-bit address and 48-bit data bus. Electrical operation supports both 5 V and 3.3 V supplies. Communication interfaces include twelve 40 MB/s link ports, four independent 40 Mbit/s serial ports, and one common serial port. The component is housed in a hermetic 308-lead ceramic quad flatpack (CQFP) package.

Feature Summary

• Quad-core architecture utilizing ADSP-21060 processors for high-density signal processing
• Integrated 16 Mbit shared SRAM accessible by all four SHARC cores
• High-speed interconnects comprising twelve 40 MB/s link ports and multiple serial ports
• Hermetic 308-lead CQFP packaging with configurable cavity orientation

Applications

• High-performance digital signal processing systems requiring parallel execution
• Complex communication infrastructure equipment
• Radar and sonar signal processing applications
• Industrial control systems demanding high throughput per unit area

Procurement Notes

Verify the specific grade suffix against the ordering guide to confirm temperature range. The B grade operates from -40°C to +100°C, while the K grade operates from 0°C to +85°C. Ensure the voltage supply requirements match the system design, as the device supports both 5 V and 3.3 V operations. Confirm the package orientation preference, as the cavity can be configured up or down during manufacturing.

Selection Notes

Select the AD14060LBF-4 when a single package solution is required to replace multiple discrete DSPs. The choice between B and K grades depends strictly on the ambient operating temperature of the target environment. Designers must account for the 308-lead pitch of 0.65 mm and the thermal resistance of 0.36°C/W when planning heat dissipation strategies for the ceramic package.

Part Context

This component belongs to the AD14060/AD14060L family, representing the initial entry into Analog Devices' high-performance DSP multiprocessor modules. It leverages the multiprocessing capabilities of the ADSP-21060 to maximize performance density. The BF-4 designation indicates the specific pin-compatible variant within the broader Quad-SHARC product line.

Replacement Considerations

Direct replacements within the same family include the AD14060 (5 V only) and AD14060L (3.3 V only). For higher performance needs, the AD14160 offers an upgraded core configuration. Verify that any substitute maintains the 308-lead CQFP footprint and hermetic sealing requirements if environmental protection is critical.
