AUSTIN, Texas � Silicon Labs’ new Global Eagle (Si4795x) and Dual Eagle (Si4796x and Si4797x) families of analog AM/FM receivers and digital radio tuners �set a new standard for scalability and automotive broadcast reception,� according to a company press release.
The Eagle families extend the field-proven performance of Silicon Labs’ tuners and receivers, which are deployed by automotive OEMs and Tier 1 suppliers. Si479xx devices leverage Silicon Labs’ patented low-IF digital architecture, delivering �superior RF performance and interference rejection.� In addition, the Si479xx family’s firmware algorithms dynamically adjust signal reception in moving cars to ensure optimal reception under the harshest field conditions.
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 simplify system design and minimize the bill of materials (BOM) by eliminating the need for an external RAM memory module for channel decoding typically required by third-party digital radio processors. The Digital Falcon family enables designs to scale from low- to high-end systems with its seamless blending capabilities for DAB/DAB+, as well as its support for Automatic Level and Time Alignment (ALTA) for HD systems.
The audio subsystem of both Eagle families provides a complete solution to synchronize, 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 equalization, loudness compensation, tone control, chime generation and audio source mixing. This flexible architecture enables integration of customer or third-party algorithms.�
