ADSP-21061LKB-160

Digital Signal Processor Dsp Overview

The ADSP-21061LKB-160 is a commercial-grade SHARC digital signal processor operating at a maximum clock frequency of 40 MHz. It delivers 120 MFLOPS peak and 80 MFLOPS sustained performance using 32-bit IEEE floating-point computation units. The device features a Super Harvard architecture with four independent buses, enabling single-cycle instruction execution and simultaneous fetch of two operands. It integrates 1 Mbit of dual-ported on-chip SRAM organized into two blocks, along with integrated I/O peripherals including serial ports, a DMA controller, and a host interface.

Digital Signal Processor Dsp Feature Summary

• Super Harvard Architecture with four independent buses for high-throughput data processing
• Integrated 1 Mbit dual-ported on-chip SRAM supporting single-cycle independent accesses
• Dual synchronous serial ports capable of up to 50 Mbps data rates with TDM multichannel mode
• On-chip DMA controller with six channels for zero-overhead data transfers

Digital Signal Processor Dsp Applications

• High-performance communications systems requiring real-time signal processing
• Graphics and imaging applications utilizing FFT and filter algorithms
• Multiprocessor DSP systems with glueless interconnection capabilities

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -160 indicates 40 MHz) against project timing requirements. Confirm package availability as the 240-lead MQFP variant may have limited stock compared to other speed grades. Check RoHS compliance status if lead-free packaging is mandatory for the assembly process.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring 40 MHz operation with 3.3 V supply voltage characteristics typical of the L-series. Ensure the design accommodates the 240-lead MQFP thermal requirements. Consider the ADSP-21061LKSZ-160 if a thermally enhanced MQFP package is preferred for higher power dissipation scenarios.

Digital Signal Processor Dsp Part Context

This component belongs to the Analog Devices SHARC family, specifically the ADSP-21061 series. It is code-compatible with the ADSP-21060 and ADSP-21062 but lacks link port functionality. The 'L' designation typically indicates 3.3 V operation, while the '-160' suffix denotes the 40 MHz speed grade.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21061LKSZ-160 is a confirmed substitute offering the same electrical specifications in a thermally enhanced MQFP package.
