ADSP-21469KBCZ-4

Digital Signal Processor Dsp Overview

The ADSP-21469KBCZ-4 is a high-performance 32-bit/40-bit floating-point digital signal processor from Analog Devices, operating at up to 450 MHz. It features a Single-Instruction, Multiple-Data (SIMD) computational architecture delivering 2.7 GFLOPS. The device includes 5 Mbits of on-chip SRAM and utilizes the Super Harvard Architecture for sustained high-speed computations. Optimized for audio applications, it integrates audiocentric peripherals such as S/PDIF transceivers, asynchronous sample rate converters, and hardware accelerators for FIR, IIR, and FFT operations.

Digital Signal Processor Dsp Feature Summary

• SIMD computational engine with two processing elements (PEX, PEY) supporting IEEE 32-bit and 40-bit floating-point formats.
• Integrated hardware accelerators for FIR, IIR, and FFT algorithms to enhance processing throughput.
• Rich peripheral set including eight serial ports (SPORT), four asynchronous sample rate converters (ASRC), and an S/PDIF transceiver.
• Supports external DDR2 memory interface with a 16-bit data bus for expanded storage capabilities.

Digital Signal Processor Dsp Applications

• High-performance audio processing and decoding
• Automotive audio systems
• Industrial instrumentation and control
• Test and measurement equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix KBCZ-4 against the manufacturer's current ordering guide to confirm package type, temperature range, and revision status. Ensure compatibility with development tools such as CrossCore Embedded Studio (CCES) or VisualDSP++ for code compilation and debugging. Check for any recent product change notices regarding pin assignments or electrical characteristics.

Digital Signal Processor Dsp Selection Notes

Select this model when high-density on-chip memory (5 Mbits RAM) and SIMD performance are required for complex audio algorithms. Compare with the ADSP-21467 if ROM-based audio decoders are needed, as the ADSP-21469 lacks internal ROM. Consider the automotive-grade variant if MediaLB interface support is necessary for vehicle networks.

Digital Signal Processor Dsp Part Context

This component belongs to the fourth-generation SHARC family, source-code compatible with previous ADSP-2136x and ADSP-2126x series in SISD mode. It represents a significant performance increase over prior generations due to the SIMD core and increased on-chip memory bandwidth.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21467 is a functional alternative within the same family but includes 4 Mbits of on-chip ROM for audio decoders. For higher performance requirements, consider the ADSP-2156x series which offers increased clock speeds and DDR3 support.
