Expanded Portfolio Includes AM/FM Radio Receivers with Integrated
Audio Processing Paired with Digital Radio Coprocessors and Data
Receivers
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Labs (NASDAQ: SLAB), a leading provider of broadcast
audio solutions for automotive infotainment, today introduced a
complete portfolio of receivers/audio processors and multi-standard
digital radio ICs designed to deliver best-in-class AM/FM and digital
radio performance for the global car radio market. The Si479xx family of
AM/FM receivers and digital radio tuners delivers a new benchmark for
car radio reception performance with on-chip audio processing at the
lowest system cost. The new Si46xx family, which includes single-chip
digital radio coprocessors and data receivers, provides an advanced
digital radio audio decoding and data reception solution for analog and
digital radio.
According to IHS Automotive, global automotive sales for 2015 will reach
88.6 million light vehicle units, with China leading the volume growth.
Many of today's vehicles feature sophisticated infotainment systems with
multiple tuner ICs and antennas to support maximal ratio combining (MRC)
for digital radio, FM phase diversity reception, Radio Data System (RDS)
info-navigation data, and digital radio standards such as HD Radio™
and Digital Audio Broadcast (DAB). Silicon Labs developed the Si479xx
and Si46xx portfolio to address the global demand for advanced car radio
technology supporting all worldwide broadcast radio bands.
The Si479xx family of analog AM/FM receivers and digital radio tuners
sets a new standard for automotive broadcast reception. Leveraging
Silicon Labs' patented low-IF digital architecture, the Si479xx family
delivers superior RF performance and interference rejection for car
radio applications. The proven RF CMOS design, combined with
comprehensive AM/FM firmware, sets a higher bar for key automotive radio
metrics, such as sensitivity in weak signal environments, selectivity in
the presence of blockers, and immunity to multipath fading and
distortion. An integrated audio subsystem provides an innovative
solution to synchronize, process and distribute digital and audio
signals in the automotive head-unit. To reduce time-to-market for
developers, Silicon Labs offers four-channel and six-channel audio
post-processing reference designs. In addition, Silicon Labs provides a
software development kit (SDK) that simplifies porting of third-party
algorithms to the audio subsystem.
Silicon Labs' Si462x data receiver family offers a comprehensive,
cost-effective platform that supports analog and digital radio by
integrating a multiband RF tuner, demodulator and channel decoder on a
single die. The Si462x receivers provide significant advances in size,
power consumption and performance over all other solutions in the market
to enable HD Radio and DAB/DAB+ data services in automotive infotainment
systems and car radios. The Si462x family's high level of single-chip
integration simplifies infotainment system design cycles.
The Si461x digital radio coprocessors provide channel demodulation and
source decoding of HD Radio and DAB/DAB+ digital radio. The Si461x
coprocessors minimize the system bill of materials (BOM) by eliminating
the external RAM memory module for channel decoding typically required
by competing digital radio processors. All Si461x/2x IC products are HD
Radio certified by iBiquity, giving automotive OEMs and Tier 1 suppliers
the assurance that these devices have gone through rigorous testing and
meet or exceed iBiquity's high-performance digital radio requirements.
Silicon Labs' complete radio system comprising receivers/tuners,
coprocessors and data receivers enables industry-leading performance at
the lowest external system BOM cost. For example, Si479xx integrated
active loop-through buffers eliminate the need for external RF
splitters, simplifying design for applications requiring a data receiver
for background scanning and real-time traffic information. The Si479xx
audio subsystem with integrated analog-to-digital converters (ADCs) and
digital-to-analog converters (DACs) and the Si461x digital radio
coprocessors with integrated RAM for channel decoding eliminate numerous
external components, resulting in significant cost savings and reduced
board area.
The Si479xx/Si46xx portfolio provides a scalable architecture
well-suited to support multiple segments across the global automotive
infotainment market. Leveraging the portfolio, Tier 1 suppliers and OEMs
can reuse their R&D investment across multiple product lines ranging
from entry level to premium automotive radio systems. For example, a
single global printed circuit board (PCB) can be designed with options
to use Si461x coprocessors or Si462x data receivers as needed to enable
RDS, HD Radio and DAB/DAB+. All Si479xx/Si46xx devices share a common
application programming interface (API), enabling developers to reuse
the same software across different product lines and market segments.
"As a leading tuner supplier for broadcast applications with more than
1.2 billion ‘radio-on-a-chip' ICs shipped to date, Silicon Labs is
committed to helping automotive OEMs and Tier 1 suppliers enhance the
performance of car radio systems while reducing system cost and
complexity," said James Stansberry, senior vice president and general
manager of Silicon Labs' Internet of Things and broadcast products. "Our
new Si479xx/Si46xx portfolio provides a complete platform for developing
a wide range of systems for the global automotive infotainment market,
ranging from entry-level car radios to multi-tuner, multi-antenna
designs."
