The audio subsystem of the Global Eagle and Dual Eagle devices provides a complete solution to synchronise, process and distribute digital and audio signals in the automotive head unit.
Silicon Labs has rolled out a flexible portfolio of car radio transceivers, tuners and coprocessors, allowing automakers and Tier 1 suppliers to address all market segments while meeting automotive quality standards.
The Global Eagle (Si4795x) and Dual Eagle (Si4796x and Si4797x) families of analog AM/FM receivers and digital radio tuners extend the performance of Silicon Labs' tuners and receivers. Si479xx devices leverage Silicon Labs' patented low-IF digital architecture for RF performance and interference rejection. In addition, the Si479xx family's comprehensive firmware algorithms adjust signal reception in moving cars to ensure optimal reception under the harshest field conditions.
The audio subsystem of both Eagle families provides a complete solution to synchronise, process and distribute digital and audio signals in the automotive head unit. To accelerate time to market, Silicon Labs provides four- and six-channel audio post-processing reference designs supporting cabin equalisation, loudness compensation, tone control, chime generation and audio source mixing. This flexible architecture enables integration of customer or third-party algorithms.
Meanwhile, the Digital Falcon (Si469x) family of digital radio coprocessors provides channel demodulation and source decoding of HD Radio and DAB/DAB+ digital signals delivering audio and data. Digital Falcon coprocessors eliminate the need for an external RAM memory module for channel decoding typically required by third-party digital radio processors. It also enables designs to scale from low- to high-end systems with its blending capabilities for DAB/DAB+, as well as its support for Automatic Level and Time Alignment (ALTA) for HD systems.
Samples and production quantities of Global Eagle and Dual Eagle receivers and tuners and Digital Falcon coprocessors are available now.
