Supports multiple tuners and antennas, expandable to high-performance systems

Silicon Labs announced the industry's most scalable, flexible, and cost-effective automotive radio solution for the global automotive infotainment market.

Silicon Labs' new Global Eagle and Dual Eagle AM/FM receivers, digital radio tuners, and Digital Falcon coprocessors enable automakers and Tier 1 suppliers to meet stringent automotive quality standards across all market segments, cost and performance levels, and digital radio standards.

OEM and aftermarket radio design products based on Silicon Labs' new product family can be scaled from low-cost single-tuner AM/FM radios to high-performance systems supporting multiple tuners and antennas, allowing automotive radio suppliers to apply their R&D efforts to various product lines using common software APIs.

The Global Eagle (Si4795x) and Dual Eagle (Si4796x / Si4797x) analog AM/FM receiver and digital radio tuner product families present a new standard for scalability and automotive broadcast reception. The Eagle product family is an extension of Silicon Labs' market-proven tuner and receiver products, and is being adopted by leading automotive OEMs and Tier 1 suppliers worldwide.

The Si479xx devices feature Silicon Labs' patented low-intermediate frequency (low-IF) digital architecture, providing superior RF performance and interference immunity. Furthermore, the extensive firmware algorithms of the Si479xx family dynamically adjust signal reception in moving vehicles, ensuring optimal reception performance even under harsh field conditions.

The two audio subsystems of the newly released Eagle product family provide a complete solution for synchronizing, processing, and distributing digital and audio signals in automotive head units. To accelerate time-to-market, Silicon Labs offers 4-channel and 6-channel audio post-processing reference designs that support cabin equalization, loudness compensation, tone control, chime generation, and audio source mixing. This flexible architecture also enables the integration of customer or third-party algorithms.
