“Always on” voice activation, noise reduction, active noise
cancelation, echo cancelation and speaker protection features
empower consumers with greater voice control over their mobile
device while delivering a superior, noise-free audio user
experience. The CS47L90 provides a premium listening experience
with SmartHIFI™ audio playback. SmartHIFI from Cirrus Logic is a
unique combination of powerful DSP processing and high-performance
analog circuits to deliver an audio experience typically associated
with high-end audio equipment, now optimized for mobile audio
playback. The CS47L90’s ultra-low power consumption, both in
standby and operational modes, also enables significant battery
life savings.
“The ability to wake up and control your mobile device using
nothing but your voice is a rapidly growing capability that
consumers expect from their smartphones,” said Carl Alberty, vice
president of marketing, Cirrus Logic. “Our products make this
always on user experience work effectively in any environment. We
combine ultra-low power sensing and voice detection with the
algorithms needed to ensure that voice-recognition commands are
executed accurately, without compromising performance or battery
life. Cirrus Logic continues to set industry standards for sound
quality and high performance audio playback—delivering sound
quality that was once reserved for high-end hi-fi home audio
equipment.”
The CS47L90 is supported on multiple application processor
platforms, enabling a consistent feature set and high performance
capability across a wide variety of handsets from leading OEMs. A
variety of interfaces allows for integration with all of the key
components in the complex architectures of the latest mobile
devices, including baseband and applications processors, wireless
audio transceivers, analog or digital MEMS microphones and boosted
speaker amplifiers. The devices support popular voice-wake trigger
engines, including Google Hotword and Sensory TrulyHandsfree. In
addition, development tools are available for customers and
third-party IP providers to develop custom solutions on the
programmable Cirrus Logic DSP core.
Hi-Fi quality now available in mobile devices
Cirrus Logic continues to develop market leading hi-fi
technology for the playback experience, innovating on all aspects
of the playback path, ensuring that the smartphone or the smart
codec inside does not limit the user listening experience.
Supporting 32-bit audio playback and integrating low series
resistance and low jitter clock circuits, the CS47L90 is designed
to ensure that the hi-fi DAC and headphone amplifier circuits
deliver a clean, transparent audio signal with flat frequency
response all the way to the output of the headphone. Combined with
dynamic adjustments to the audio playback based on the content
being consumed, the new flagship smart codecs from Cirrus Logic
deliver the best audio experience with minimal power consumption to
allow users to enjoy their music longer.
