“New digital connectivity in mobile devices, including the Lightning-based interface, is creating opportunities for OEMs to innovate in product design and is accelerating the transition from analog- to digital-connected products within today’s billion-unit headset and headphone market,” said Carl Alberty, vice president of Audio Products Marketing, Cirrus Logic. “Our MFi reference design provides a complete high-performance, digital-headset solution and a reference iOS application to support the rapid development of these emerging consumer products.”
The MFi Headset Development Kit demonstrates the advantages of Lightning-connected headsets over conventional analog headsets. For example, digital connectivity with an integrated, high-performance DAC and headphone driver delivers high-fidelity audio to the headphone speakers. In addition, Lightning-connected headphones can interact with an iOS app to create a more custom audio experience, such as personalized EQ settings.
The Cirrus Logic MFi Headset Development Kit includes a form factor reference design and a development board for debugging, as well as MCU programming and audio performance measurement. Both boards are pre-programmed to support a demonstration of high-performance digital audio playback and voice capture, enabling developers to evaluate a prototype within minutes. The design can be adapted to any headset form factor, including earbuds and over-the-ear designs.
The Cirrus Logic HiFi MFi Headset Development Kit is available to MFi licensees through the MFi procurement portal.
