MultiPhy

The company's product line centered on its FlexPhy family of chips. These system-on-a-chip (SoC) solutions utilized advanced CMOS-based ADC designs and proprietary DSP algorithms, including Maximum Likelihood Sequence Estimation (MLSE), to enable high-speed communication. The technology was designed for both direct detection and coherent transmission, aiming to set new benchmarks for cost and performance in passing large data volumes through optical networks.

MultiPhy operated on a fabless business model, meaning it designed the chips but outsourced the manufacturing process. The company targeted clients in the high-speed communications sector, particularly those building infrastructure for data centers. In a strategic partnership, MultiPhy collaborated with Semtech to pair its FlexPhy chips with Semtech's laser drivers and transimpedance amplifiers, offering a comprehensive solution for single-wavelength 100-Gbps designs.

Throughout its history, MultiPhy secured significant venture capital funding. The company raised a total of $24.2 million, including a Series C round of $17 million in January 2016. Investors included Kreos Capital, Vertex Ventures Israel, Viola Group, Molex Ventures, and Semtech, which became one of the largest stakeholders. Despite these milestones, the company is now listed as out of business.
