Cirrus Logic, Intel, and Microsoft to collaborate on PC reference design

Date: 16/02/2024
Cirrus Logic, Intel, and Microsoft are working together to develop a new PC reference design. This collaboration integrates Cirrus Logic's audio and power semiconductor ICs with Intel's upcoming client processor, codenamed Lunar Lake, aiming to enhance laptop audio and improve battery life and device design.

The design includes the Cirrus Logic CP9314 high-efficiency power converter, minimizing heat generation and extending battery life. This technology enables sleeker device designs with reduced fan noise. Cirrus Logic's low-power CS42L43 SmartHIFI codec and CS35L56 smart amplifiers are designed to deliver better audio quality while optimizing power usage. The codec improves headset audio transparency, reducing power consumption by 50% compared to legacy codecs.

The reference design is adaptable across different processors, speakers, and notebook designs, providing OEMs with flexibility. It supports the transition to new interface standards and frameworks, ensuring compatibility and ease of integration.By optimizing power consumption, the design enables longer battery life and allows for smaller, thinner notebooks, enhancing portability.

“Cirrus Logic is delivering value to the PC market with immersive audio and high-efficiency power conversion solutions,” said Carl Alberty, vice president of Cirrus Logic’s Mixed-Signal Products group. “Until now, our collaborations with Intel and Microsoft have only included our audio components, but now our power conversion products are expanding the offering. We are excited to help our customers build laptops that elevate the laptop experience for consumers with fantastic sound and sleek, quiet, and power efficient designs.”

“Intel is committed to accelerating every aspect of the PC experience,” said Ken McKee, general manager of Client Customer Engineering and vice president of the Client Computer Group for Intel. “Companies like Cirrus Logic help us make this vision a reality by enabling innovation at scale. This collaboration enhances the PC experience, delivering more advantages to both the industry as a whole and individual consumers.”
