Skyworks at Electronica 2026

At Electronica, Skyworks will use the SKY4680x family to transform a two-channel audio source into a multi-channel listening experience. The demonstration will also feature a Skyworks-developed Edge AI siren detection application, extending the company's award-winning AI expertise into automotive applications.

Together with support for customer-developed algorithms and application-specific software, the demonstration illustrates how the SKY4680x family can serve as both a high-performance automotive audio DSP and a flexible Edge AI processing platform.
