New Cirrus Logic audio amplifier/codec solution
is part of SoundWire-ready Intel® reference design offering PC OEMs
a scalable, frustration-free migration to new audio
specification
Cirrus Logic (Nasdaq: CRUS) is offering an advanced audio
solution to help ease PC manufacturers’ migration to the MIPI
SoundWire® interface (1.2.1 specification) for a richer, more
immersive audio experience. Along with this recently introduced
audio solution optimized for the PC platform, Cirrus Logic is
collaborating with industry leaders Intel® and Microsoft to help
ease the transition to the SoundWire interface and scalable
architecture to deliver even better audio in next-generation laptop
designs. At the heart of the Cirrus Logic advanced, low-power audio
solution are the company’s recently announced CS35L56 smart
amplifier and CS42L43 Smart HIFI™ codec that are included in the
Intel SoundWire-ready reference design aimed at helping laptop
designers make a smooth migration to the new specification.
“The migration toward the SoundWire interface brings needed
improvement and forward progress to PC audio design, but for OEMs
it still means a platform change,” said Peter Cooney, founder of
SAR Insights. “Industry leaders such as Intel, Microsoft, Cirrus
Logic and others have not only been working toward enriching future
audio experience for users but also aiding PC OEMs in migrating
more easily to the new SoundWire interface.”
To do this, Cirrus Logic offers a combined PC audio solution
that contains a smart amplifier and codec that lowers the overall
bill of materials. Both the Cirrus Logic CS35L56 smart amplifier
and CS42L43 SmartHIFI codec provide for simple integration with a
SoundWire Device Class Audio (SDCA) manager and are designed to
work within Microsoft’s ACX framework.
“At Cirrus Logic, our product development has not only been
engineered to offer immersive audio but also help OEMs accelerate
their design process to be compatible with upcoming SoundWire
specifications,” said Carl Alberty, vice president of Cirrus
Logic's Mixed-Signal Products group. “This includes working closely
with industry leaders, such as Intel and Microsoft, on the MIPI
SoundWire integration design-in so that our customers come away
with a more streamlined and differentiated audio solution that can
scale throughout their product offerings.”
“Intel has been working diligently within the industry, and with
the Audio Working Group, to help accelerate the advancement of the
PC platform and improve audio performance,” said Ken McKee, general
manager of Client Customer Engineering and vice president of the
Client Computer Group for Intel. “Companies like Cirrus Logic that
align with these goals help make the transition easier for OEMs to
adopt so that greater innovation can be achieved. Such
collaborative industry efforts benefit PC OEMs with more flexible
design while offering the user a richer audio experience.”
Smart Audio Solution for Smooth, Scalable Design-in
Offering both flexibility and extendibility, Cirrus Logic’s
smart amplifiers and codecs offer a combined hardware, firmware and
Windows driver solution that is compatible across industry-leading
processors and with any number of speakers. By choosing the number
of CS35L56 amplifiers to pair with the CS42L43 codec, OEMs can
scale their solutions for performance and value while simplifying
their SoundWire design implementations.
As part of the SoundWire-compatible reference design from Intel,
Cirrus Logic’s CS35L56 smart amplifier helps PC manufacturers
deliver rich audio with deeper bass, balanced sound and dynamic
range from compact multiple-speaker designs in the thinnest of
laptops. For a top-tier headset audio experience, the Cirrus Logic
CS42L43 PC audio codec delivers great voice clarity, high dynamic
range and low distortion.
MIPI SoundWire Specification
The MIPI SoundWire specification was introduced by the MIPI
Audio Working Group in 2014 to help consolidate many of the key
attributes in mobile and PC audio interfaces to provide a common,
comprehensive interface and scalable architecture to enable audio
features and functions in multiple types of devices. The v1.2.1
specification (June 2022) supports the use of advanced amplifiers
and microphones and helps optimize speaker protection, microphone
power and performance, noise cancellation and always-listening
audio input.
