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.
