d) Licensee agrees that it shall not take any actions whatsoever that could or would cause the Content, Software, or Modifications or any portion thereof to become subject to the GNU General Public License (GPL), GNU Lesser General Public License (LGPL), Mozilla Public License (MPL), Artistic License, Apache License, Q Public License, IBM Public License, or any other open source license requiring the distribution of the Software or Modifications or any part thereof in any code format.
e) In the event Licensee makes modifications to the Software made by or on behalf of Licensee (each a "Modification"); Licensee shall notify ON Semiconductor of any Modifications and provide ON Semiconductor with a source code formatted copy of each such Modification within thirty (30) days of making such Modifications. ON Semiconductor shall own any Modifications to the Software.
f) Licensee shall retain, and shall require each Customer to retain, all copyright and other notices within the Content, Software and Modifications developed by Licensee hereunder.
g) Licensee may only distribute the Software or Modifications to its Customers pursuant to a written license agreement. At a minimum such license agreement shall safeguard ON Semiconductor's ownership rights to the Software. Such license agreement may be a "break-the-seal" or "click-to-accept" license agreement.
h) The Content is licensed for use only with the ON Semiconductor Products. Use of the Content with non-ON Semiconductor Products is not licensed hereunder.

2.2 Ownership; No Implied Licenses. Subject to the licenses expressly granted herein by ON Semiconductor to Licensee, ON Semiconductor (and/or its licensors/suppliers) retains all rights, title and interest in and to the Content and all patents, copyrights, trademarks, trade secrets, and all other proprietary or intellectual rights therein. ON Semiconductor (and/or its licensors/suppliers) reserves all rights not expressly granted hereunder, and there are no implied licenses granted by ON Semiconductor hereunder. Certain elements of the Content may be provided in files/data formatted for use with or by certain third party software/tools/products.

Ezairo® 5900

Dual-core Flexibility | High Fidelity | Ultra-low Power | Finer Granularity



SoC Single Die 130nm


Dual-core Flexibility

The Ezairo 5900 series features two independent and fully programmable signal processing cores, each with unique attributes. Both cores ensure an evenly balanced work load for sophisticated audio processing algorithms, optimizing power consumption and processing efficiency while delivering maximum flexibility.

The highly flexible accelerator engine performs super efficient, low-delay, high-fidelity filterbank processing in the time domain or frequency domain, set up in uniform or non-uniform bands.

The fully programmable 24-bit dual-MAC DSP core is optimized to run advanced, computationally intensive hearing aid algorithms. It is also used to configure the entire system and coordinate the signal data flow.

High Fidelity

Not all DSP technology for hearing aids is equal. Some systems only capture a part of the full sound environment. Capturing a wide dynamic range is critical for high quality digital processing and rendering.

The Ezairo 5900 series provides up to 110dB of input dynamic range to capture the full depth of sound. Combined with extremely low system noise and high precision signal processing, hearing aid manufacturers can craft state-of-the-art devices with exceptional sound quality.

Dynamic Range

Ultra-low Power

Today's advanced audio processing algorithms demand greater computational capability. As processing intensity increases, so does the drain on the battery. Since hearing aid users don't want to change batteries any more frequently than they do now, algorithm innovation is constrained.

The Ezairo 5900 series gives algorithm developers the freedom to implement sophisticated next-generation audio processing techniques without sacrificing battery life.

Manufactured using a 130-nanometer process combined with a highly optimized architecture design, Ezairo delivers twice the computing power of previous generation DSP systems for even less power consumption.

Finer Granularity

The enhanced precision provided by 24-bit processing is somewhat comparable to the superior details captured by high megapixel digital cameras. Being able to divide and analyze different sound frequencies with greater precision enables a much more accurate reproduction of the sound environment.

With increased precision, the Ezairo 5900 series enables today's adaptive hearing aid algorithms such as feedback cancellation, noise reduction or beamforming to perform much more efficiently - producing a richer audio experience for the user.
