Inphi Corporation is a U.S.-based semiconductor firm that designs and manufactures high-speed analog and mixed-signal components alongside optical subsystems tailored for networking OEMs, cloud service providers, and telecommunications companies. Situated in Santa Clara, California, the company’s offerings encompass linear transimpedance amplifiers, modulator drivers, optical physical layer devices, coherent DSPs, and silicon photonic subsystems aimed at long haul, metro, and data center sectors. Since April 2021, Inphi has functioned as a subsidiary under Marvell Technology, Inc..
History
Established in 2000 by Gopal Raghavan, Tim Semones, and Loi Nguyen, Inphi initially concentrated on delivering high-speed analog, digital signal processing (DSP), and optical semiconductor solutions for cloud infrastructure and service providers. The company broadened its market reach through key acquisitions: purchasing Cortina Systems in 2014 for $131 million enhanced its portfolio in high-speed interconnects and optical transport products. In 2016, it sold its memory product division to Rambus for $90 million while acquiring ClariPhy Communications for $277 million to bolster its coherent optical technology capabilities.
In 2019, Inphi expanded further by acquiring eSilicon for $216 million in cash plus debt assumption, integrating advanced 2.5D packaging technology, SerDes expertise, and bespoke silicon design into its product suite. February 2020 saw the launch of the industry’s first 800 Gbps PAM4 electro-optics platform, reinforcing Inphi’s position at the forefront of ultra-high-speed data transmission.
In October 2020, Marvell Technology, Inc. declared an $8.2 billion deal to acquire Inphi to strengthen its presence within cloud infrastructure and 5G markets. This acquisition was finalized in April 2021, merging Inphi’s cutting-edge semiconductor technologies into Marvell’s global business operations.
