combines smart amplifier and low-power codec for enhanced speaker
and headphone listening experience
COMPUTEX TAIPEI – Cirrus Logic (Nasdaq: CRUS) announced
today a premium audio solution built specifically for PCs that
enables a louder, more immersive audio experience, whether
listening to voice calls and music from the small internal speakers
on ultrathin laptops or from headphones. Cirrus Logic’s
PC-optimized audio solution includes the Cirrus Logic®
CS35L56 smart amplifier packed with processing power to deliver
higher performing audio and the low-power CS42L43 SmartHIFI™ PC
audio codec that integrates a MIPI SoundWire®
interface (v1.2). This advanced audio solution also simplifies
design for PC manufacturers and contributes to a reduction in the
total number of components to save board space and lower bill of
material costs.

According to Phil Solis, research director, Connectivity and
Smartphone Semiconductors at IDC, “The PC market continues to shift
towards thinner and lighter form factors that even approach the
thickness of smartphones. At the same time, both consumer and
commercial users want better audio quality from their laptops,
whether that is for gaming, video or video conferencing
applications. This requires higher-performing audio solutions with
lower BOM costs and sizes.”
PC-Optimized Audio Solution Delivers Big Sound
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 on the thinnest of
laptops. The CS35L56 smart amplifier includes onboard DSP, sensing
hardware, notebook battery voltage boost, and protection and
enhancement algorithms to deliver industry-leading PC audio that
maximizes loudness and increases quality and consistency while
minimizing rattle and vibration. The CS35L56 amplifier consistently
extracts maximum performance from novel form factors, such as 360s
and detachable 2-in-1s and folios, and new high-excursion and
force-cancelling speakers without noticeable speaker
degradation.
The CS42L43 PC audio codec delivers a top-tier headset audio
experience with great voice clarity, high dynamic range and low
distortion. Because headphones vary greatly in acoustic
characteristics, it’s important that OEMs consider headphone types
in their design process. Otherwise, users may hear different sound
from different headphones even from the exact same laptop. Cirrus
Logic’s CS42L43 codec helps OEMs deliver more transparent,
consistent premium audio quality across headphone types. With 50
percent lower power than other available solutions, the CS42L43
audio codec also contributes to longer PC battery life.
Less Board Space and Lower Bill of Materials Costs
Cirrus Logic’s advanced audio solution also simplifies design
and lowers material costs for PC manufacturers. The CS42L43 audio
codec is available in a 13mm2 chip scale package, which contributes
to a combined solution that is more than 50 percent smaller
compared to competing products. The PC-optimized solution enables
designs with lower cost and less waste due to lower power
consumption, reduced board space and fewer components.
Frustration-Free PC Audio Design
Cirrus Logic’s PC audio solution enables a frustration-free,
simpler design process and eases OEM’s transition to the industry’s
new SoundWire® interface (v1.2). The CS35L56 amplifier
provides for simple integration with a SoundWire®
Device Class Audio (SDCA) manager and is designed to work within
Microsoft’s ACX framework.
Offering both flexibility and extendibility, Cirrus Logic’s
audio solution combines a hardware, firmware and Windows driver
solution, making it 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 also can scale
their solutions for performance and value.
“As users rely more and more on their laptops in their daily
lives, whether it’s in hybrid working environments or for
entertainment, today’s laptops need solutions that promise big
sound out of small spaces while addressing the industry transition
to the SoundWire® interface,” said Eric Eklund,
director of Marketing and Applications for Cirrus Logic’s
Mixed-Signal Products Group. “Cirrus Logic answers this need with a
premium PC-built audio solution that enables frustration-free OEM
design and loud, immersive audio whether listening from the
speakers on your laptop or using headphones.”

The 55-nm process CS35L56 is available in a commercial-grade
34-pin QFN package. The CS42L43 audio codec is available in a
commercial-grade, 70-ball WLCSP (wafer-level chip scale package)
