New Si4790x Automotive Receiver Family Scales from Economical,
Single-Tuner Designs to Premium, Multi-Tuner Car Radio Systems
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Labs (NASDAQ: SLAB), a leader in high-performance, analog-intensive,
mixed-signal ICs, today introduced the industry's most advanced
automotive tuner IC family designed to deliver best-in-class AM/FM and
HD Radio/DAB/DMB digital radio performance for demanding car
radio systems. Silicon Labs' next-generation Si4790x tuner IC family
delivers a new benchmark for car radio reception performance while
delivering the lowest system cost. The Si4790x family also provides
exceptional flexibility and scalability for Tier 1 automotive
infotainment suppliers and aftermarket car radio makers worldwide.
The Si4790x family leverages Silicon Labs' patented digital low-IF
architecture and RF in CMOS technology pioneered more than 12 years ago.
Silicon Labs introduced its first single-chip broadcast audio IC
products nearly 10 years ago, redefining how AM/FM tuner ICs were
designed into analog-intensive consumer electronics products by
providing a highly integrated solution that reduced component count by
more than 90 percent and board space by more than 60 percent. To date,
Silicon Labs has shipped more than 1.2 billion "radio-on-a-chip" ICs,
culminating with the introduction of the Si4790x family, the industry's
most advanced automotive tuner IC.
The superior linearity of the Si4790x tuner's integrated RF front-end,
combined with comprehensive AM/FM firmware running on a high-performance
on-chip radio DSP, sets a new 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.
According to IHS Automotive, global automotive sales reached nearly 83
million vehicles in 2013 and will climb to 85 million vehicles in 2014.
Many of these vehicles feature sophisticated infotainment systems with
multiple tuner ICs and antennas to deliver FM phase diversity reception,
receive Radio Data System (RDS) data for info-navigation systems, and
support digital radio standards such as HD Radio prevalent in the U.S.
market and Digital Audio Broadcast (DAB), the leading European standard.
To address today's global market, the Si4790x tuner family supports all
worldwide broadcast radio bands including AM/FM, longwave (LW),
shortwave (SW), NOAA weather band, FM RDS decoding, and AM/FM HD Radio
and DAB reception (Band-III and L-band).
The Si4790x family's scalable architecture is well suited for the global
automotive market, enabling developers to optimize system configurations
to match specific automotive OEM requirements worldwide. Leveraging the
Si4790x family, Tier 1 suppliers can make the most of their R&D
investment across multiple product segments, from cost-effective
single-tuner designs to premium multi-tuner systems, with one modular
architecture. All tuner devices in the Si4790x family share the same
application programming interface (API) allowing infotainment system
developers to reuse the same software across different product lines and
market segments.
The Si4790x tuners' high level of single-chip integration enables
developers to significantly reduce board space, the external bill of
materials and overall system cost. The tuners integrate active
loop-through buffers for all radio bands, eliminating external active
splitters. Integrated active loop-through buffers greatly simplify the
front-end RF design, further reducing cost.
"The Si4790x tuner ICs set a new standard of excellence for car
broadcast reception and RF performance," said James Stansberry, senior
vice president and general manager of Silicon Labs' Internet of Things
and broadcast products. "Designed to be a truly global automotive radio
solution, the Si4790x family supports all leading broadcast standards
worldwide, and our scalable architecture enables infotainment system
suppliers to leverage their investments across multiple product lines
ranging from entry-level car radios to cutting-edge multi-tuner,
multi-antenna radios for premium vehicles."
