Highly Integrated CP2114 Device Supports Leading Codecs and DACs for
USB Audio Applications
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today introduced the industry's
first crystal-less USB-to-I2S audio bridge designed to
support a wide range of codecs and digital-to-analog converters (DACs)
used in USB-based audio applications. The new CP2114 audio bridge chip
simplifies the process of transferring audio data from USB to I2S
without time-consuming code development, speeding time to market for USB
audio accessories such as speakers, headphones, music boxes,
point-of-sale terminals, navigation systems and VoIP systems.
USB system development often involves significant expertise, design
effort and cost to overcome implementation issues ranging from
compatibility to poor performance. USB-to-I²S audio data transfer also
requires sophisticated clock synchronization, which poses complex
development challenges. To address these needs, Silicon Labs' CP2114
audio bridge provides a highly-integrated, plug-and-play solution for
streaming audio between USB and I²S.
The CP2114 audio bridge integrates a USB 2.0 full-speed function
controller, a USB transceiver, crystal-less oscillator, one-time
programmable ROM, UART, IIC and I2S interface into a
single-chip solution. The device's innovative crystal-less architecture
eliminates the need for external clock crystals and associated
components, reducing audio system BOM cost and design complexity. The
CP2114 audio bridge also requires no external memory when combined with
a codec or DAC, further minimizing system BOM cost.
The CP2114 audio bridge supports multiple mainstream DACs and codecs
from Wolfson Microelectronics, Cirrus Logic and Texas Instruments,
giving customers the flexibility to implement their own preferred audio
chipset solution. Silicon Labs offers evaluation kits pre-populated with
these popular DAC and codec platforms to further speed design time.
"Fast time to market and BOM cost reduction are critical requirements in
today's competitive audio market, and by collaborating with Silicon
Labs, we are able to help our customers bring cost-effective USB audio
solutions to market quickly," said Eddie Sinnott, portfolio and strategy
director at Wolfson Microelectronics. "Wolfson is a global leader in the
supply of high-performance mixed-signal semiconductor devices and
high-definition audio solutions to the consumer electronics market, and
the combination of Wolfson multi-channel and stereo DAC products and
Silicon Labs' CP2114 audio bridge chip provides a best-in-class platform
for an array of cost-sensitive consumer audio products."
"Cirrus Logic and Silicon Labs have a long history of working closely
together in the audio market to deliver compelling platforms that help
our customers reduce cost and speed time to market," said Carl Alberty,
director of marketing for audio products at Cirrus Logic. "Cirrus Logic
is recognized for our broad portfolio of ultra-low power,
high-performance codecs, so together with Silicon Labs' CP2114 audio
bridge, OEMs benefit from a turnkey USB audio platform that allows them
to differentiate and excel in the competitive audio market."
The CP2114 audio bridge uses the standard USB audio device class that is
natively supported by most operating systems. USB audio class
compatibility eliminates the need to develop and install custom USB
software drivers. Host programming capabilities also enable developers
to configure practically any external codec or DAC and perform in-field
upgrades.
"As a leading supplier of USB interface devices, we make it easy and
cost-effective for our customers to implement USB connectivity in their
embedded designs," said Mike Salas, vice president and general manager
of Silicon Labs' microcontroller products. "Silicon Labs' CP2114 device
is the most developer-friendly USB-to-I²S audio bridge solution
available, vastly simplifying USB audio peripheral design."
Pricing and availability
Samples and production quantities of the CP2114 USB-to-I²S audio bridge
are available now in small-footprint 5 mm x 5 mm QFN packages optimized
for space-constrained portable audio applications. The CP2114 device is
priced at $1.13 (USD) in 10,000-unit quantities.
The CP2114EK, priced at $49 (USD MSRP), enables developers to evaluate
and customize their USB-to-I²S bridge applications through GPIO, UART
and IIC peripherals. Silicon Labs also offers additional CP2114
evaluation kits, priced at $82 (USD MSRP), that are optimized for USB
audio applications based on popular codec and DAC platforms.
