    Description

    Alphawave Semi enables tomorrow's future by accelerating the critical data communication at the heart of our digital world – from seamless video streaming to AI to the metaverse and much more.

    Our technology powers product innovation in the most data-demanding industries today, including data centers, networking, storage, artificial intelligence, 5G wireless infrastructure, and autonomous vehicles.

    Customers partner with us for mission-critical data communication, our innovative technologies, and our proven track record. Together, we enable the next generation of digital technology.
    The
    Embedded Software / Firmware Team at Alphawave Semi develops critical embedded software that powers high-performance multi-standard Serializer/Deserializer (SerDes)

    PHY IP used in next-generation data center, AI/ML, automotive, and compute applications.
