These extensive audio features, which have previously been limited to
flagship smartphones and tablets, empower consumers with greater voice
control over their mobile device while delivering a superior, noise-free
audio playback experience. The CS47L15 provides a premium listening
experience featuring Cirrus Logic SmartHIFI, a unique combination of
powerful DSP processing, ultra-low power consumption and high-quality
audio playback typically associated with high-end audio equipment. Its
ultra-low power performance (25 microwatts standby operation, 2.6
milliwatts headphone playback) ensures significant battery life savings.
“Our newest smart codec enables us to deliver important audio and voice
technology to new segments of the market, including a broader range of
smartphone models and emerging applications such as high performance
digital headsets,” said Carl Alberty, vice president of marketing,
Cirrus Logic. “As voice control continues to grow in popularity as an
interface for consumer devices, we are focused on delivering features
that enhance the overall user experience and make great sounding audio
available to more and more mobile consumers.”
The small component size, low power dissipation, hi-fi quality audio and
world-class stereo separation (-110 dB crosstalk) of the CS47L15 make
this an ideal choice for the growing number of digital headsets. The
CS47L15’s integrated equalizer and programmable DSP enable optimized
digital audio quality, allowing OEMs to create their own “signature
sound” and deliver an enhanced user experience compared to analog
headsets.
The CS47L15 elevates the hi-fi audio experience, offering clear,
transparent and natural audio playback, with a flat frequency response
across the full HD audio bandwidth. Its low output impedance ensures
consistent audio performance regardless of the headphone connected. A
low-latency monitoring path allows for enhanced KTV (karaoke), a hugely
popular app in Asia, through such features as realistic room
reverberation and ambient effects to further enhance the user
experience. In addition, previously high-end audio features, such as
noise reduction and echo cancelation, combine to significantly enhance
audio and voice conversation quality.
The CS47L15 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 device supports
popular third-party 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.
