RF2Digital

RF2Digital provides a comprehensive range of automotive Software-Defined Radio (SDR) solutions designed to operate on Arm®-based System-on-Chips (SoCs) in combination with ST RF tuner ICs. These solutions encompass all digital radio standards on a global scale and are available in various configurations, ranging from core library types to complete radio stacks.

RF2Digital also provides full technical consulting and support services to help customers implement SDR architectures, either as original development or migration of existing legacy platforms.

• α-Infuser^TM: The foundational SDR solution, operating as a core library. It supports a complete array of digital radio standards such as DAB/DAB+, DMB, DRM/DRM+, HDRadio, and CDR. This exceptional versatility is achieved by harnessing digital I/Q data from RF tuners belonging to the TDA770x and STA7xx families. The effectiveness and reliability of these combinations have been widely recognized and well-adopted in the market.
• α-Trinity^TM: This replicates the conventional chipset-based architecture, covering the Alpha-Infuser, an advanced audio seamless linking feature, and all tuner interfaces between the SoC and the TDA770x and STA7xx RF tuner families within a flexible software framework. This allows customers to seamlessly integrate the framework into their systems, effortlessly inheriting the functionalities of legacy setups.
• α-Orion^TM: This software package offers a comprehensive radio subsystem, supporting AM/FM analog radio using the TDA770x family as well as all digital radio standards using the TDA770x and STA7xx RF tuner families. It includes the Alpha-Trinity framework along with the radio middleware (Radio Manager), allowing the customer to focus solely on developing the user HMI part.

RF2Digital in STMicroelectronics ecosystem

After years of collaboration, the combination of RF2Digital’s SDR solution with ST digital output RF tuners has undergone extensive optimization and demonstrated its excellence across multiple mass production runs. This optimization extends to the SoC interface and system-level cost-effectiveness, allowing customers to seamlessly implement the validated hardware and software architecture. The results of these efforts are showcased in a range of demo platforms utilizing nearly all available automotive-grade SoCs.
