ADSP-21469KBCZ-3

Digital Signal Processor Dsp Overview

The ADSP-21469KBCZ-3 is a high-performance 32-bit/40-bit floating-point digital signal processor from Analog Devices, belonging to the SIMD SHARC family. It features a Super Harvard Architecture with up to 450 MHz operating frequency and 5 Mbits of on-chip RAM. The device includes hardware accelerators for FIR, IIR, and FFT operations, supporting 2.7 GFLOPS at maximum speed. It integrates audiocentric peripherals such as S/PDIF transceivers, asynchronous sample rate converters, and eight serial ports via a flexible Signal Routing Unit (SRU).

Digital Signal Processor Dsp Feature Summary

• SIMD computational architecture with two processing elements (PEX, PEY) delivering up to 2.7 GFLOPS at 450 MHz.
• 5 Mbits of on-chip SRAM and dedicated hardware accelerators for FIR, IIR, and FFT algorithms.
• Integrated Digital Applications Interface (DAI) featuring S/PDIF, four Asynchronous Sample Rate Converters (ASRC), and eight SPORTs.
• 16-bit DDR2 memory interface supporting external memory expansion up to 2 Gbits.

Digital Signal Processor Dsp Applications

• High-performance audio processing and professional audio equipment.
• Automotive audio systems and infotainment.
• Industrial instrumentation and test equipment requiring real-time decision execution.
• Motor control and power conversion applications utilizing PWM capabilities.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KBCZ-3' against the manufacturer's current ordering guide, as datasheet revisions may update package or temperature specifications. Confirm RoHS compliance status and lead-free soldering requirements prior to integration. Ensure development tools like CrossCore Embedded Studio are compatible with the target revision.

Digital Signal Processor Dsp Selection Notes

Select this model over the ADSP-21467 if on-chip ROM-based audio decoders are not required, as the 21469 lacks the factory-programmed decoder ROM found in the 21467 variant. Consider the automotive-qualified version if extended temperature ranges or AEC-Q100 certification are necessary for the application environment.

Digital Signal Processor Dsp Part Context

This component is part of the fourth-generation SHARC processor family, designed to offer double the performance of previous generations through increased on-chip memory and hardware accelerators. It maintains source code compatibility with earlier SHARC models like the ADSP-2136x and ADSP-2126x when operating in SISD mode.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21467 serves as a functional alternative within the same package if ROM-based audio decoding features are needed. For higher performance requirements, the ADSP-2156x series offers increased clock speeds and DDR3 support but requires architectural adaptation.
