Radio solution solves automotive industry challenge

A scalable, flexible and cost-effective car radio solution for the global automotive infotainment market has been introduced by Silicon Labs.

The new portfolio of Global Eagle and Dual Eagle AM/FM receivers and digital radio tuners, and Digital Falcon coprocessors is said to enable automakers and Tier 1 suppliers to address all market segments, cost and performance levels, and digital radio standards while meeting automotive quality standards.

According to the company, radio designs based on the portfolio can scale from low cost, single-tuner AM/FM radios to high-performance systems with multiple tuners and antennas, all with a common software API.

Silicon Labs claims to be the only automotive radio solution provider offering a scalable hardware/software platform that enables car radio suppliers to address multiple markets with a common radio hardware and software design.

The Global Eagle (Si4795x) and Dual Eagle (Si4796x and Si4797x) families of analogue AM/FM receivers and digital radio tuners leverage the company's patented low-IF digital architecture. In addition, the Si479xx family’s comprehensive firmware algorithms dynamically adjust signal reception in moving cars to ensure optimal reception under the harshest field conditions.

To accelerate time to market, the company provides four- and six-channel audio post-processing reference designs supporting cabin equalisation, loudness compensation, tone control, chime generation and audio source mixing. The architecture is said to enable integration of customer or third-party algorithms.

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.

According to the company, Digital Falcon coprocessors simplify system design and minimise the BOM by eliminating the need for an external RAM memory module for channel decoding.

The Digital Falcon family is also said to enable 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.
