AUSTIN, Texas�Silicon Labs, a provider of broadcast audio solutions for automotive infotainment, today introduced a portfolio of receivers/audio processors and multi-standard digital radio ICs designed to deliver high performance AM/FM and digital radio for the global car radio market. The Si479xx family of AM/FM receivers and digital radio tuners are designed to achieve a new benchmark for car radio reception performance with on-chip audio processing at the lowest system cost; the 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.
�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�
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 for digital radio, FM phase diversity reception, Radio Data System info-navigation data, and digital radio standards such as HD Radio�and Digital Audio Broadcast. 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 leverage Silicon Labs� patented low-IF digital architecture for superior RF performance and interference rejection for car radio applications. The RF CMOS design, combined with comprehensive AM/FM firmware, sets a high 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.
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 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.
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 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.�
