The Si469xx product family supports advanced capabilities such as Maximal Ratio Combining (MRC) and seamless linking of digital radio, analog radio and Internet Protocol content. With its integrated customer-programmable microcontroller (MCU), the Si469xx can significantly reduce bill of materials (BOM) costs by eliminating the need for an external MCU and its support components. Software design is simplified through several improvements, including a Demod/Tuner Manager that relieves system developers from having to program low-level radio control functions.
Radios in automobiles have historically been implemented in the head unit (HU) or cockpit system located in the dashboard. However, increasingly radio tuners are implemented in a separate module, often as a remote tuner module (RTM). The RTM offers benefits including reduced cable weight and the ability to design and qualify the radio for use across car models, which decouples it from the evolution of the HU/cockpit system. The cable weight reductions are a result of replacing RF coaxial cabling to the HU with a much lighter twisted pair cabling, typically accomplished with ADI A2B™ technology, which is optimized for automotive digital audio applications, or ethernet.
By leveraging separate tuner and coprocessor ICs,
“The integration of the Si469xx product family from
“In recent years, A2B technology has become the industry’s standard for low-latency digital audio connectivity. Our innovation is uniquely tailored for the RTM use case, where it not only offers substantial performance enhancements, but also drives a reduction in overall system costs,” said
“Building on the unparalleled scalability of Skyworks’ automotive radio product portfolio with the added benefits of improved performance, lower system cost and ease of use, the Si469xx family of products enhances our ability to address the needs of future IVI systems by delivering best-in-class capability, flexibility and affordability to our customers,” said
