α-Infuser™ is a versatile, highly effective, and reliable SDR solution that supports a complete array of digital radio standards, including DAB/DAB+, DMB, DRM/DRM+, HDRadio®, and CDR. It achieves exceptional versatility by harnessing digital I/Q data from RF tuners belonging to the TDA770x and STA7xx families. Widely recognized and adopted in the market, α-Infuser™ provides a cost-effective, scalable, and future-ready solution that is flexible, HW, and OS agnostic.
Thanks to the distinctive capabilities of ST's tuner products and their compatibility with α-Series solutions, the High-Speed I2S (HS-I2S) physical interface on SoCs can be fully leveraged and optimized. As an illustrative instance, while other RF tuners necessitate a minimum of 1x I2S and 2x HS-I2S ports on a SoC to support a typical radio configuration in America, ST's tuner requires only 1x HS-I2S. This streamlined approach not only resolves numerous challenges in system design but also augments potential future upgrades.
