Overview

The DSPB56725AF is a high-performance multi-core audio processor based on the dual 24-bit DSP56300 architecture, operating at up to 250MHz. It is designed for intensive digital signal processing in consumer and professional audio systems, featuring a 1.2V core for efficient power consumption and integrated interfaces like SAI and S/PDIF.

Why Choose This Part

This dual-core architecture allows for parallel processing of complex audio streams with a dedicated 112kB on-chip RAM and specialized ESAI and S/PDIF interfaces. Its 250MHz clock rate provides significant headroom for real-time 24-bit audio manipulation while maintaining a low standby current of 40uA.

Applications

Home Theater Systems
Processing multi-channel audio formats and room correction algorithms in AV receivers and HTIB units.
Digital Audio Mixers
Handling real-time effects and signal routing in professional audio mixing consoles.
Car Audio Processors
Executing sophisticated equalization and time-alignment for high-fidelity automotive sound systems.
Instrument Effects
Providing low-latency digital signal processing for electronic musical instrument effect pedals.
