eTopus designs ultra-high speed mixed-signal semiconductor solutions for high-performance computing and data center applications. Our ultra-high speed SerDes is adopted by global major players to be used in storage, enterprise, and hyperscale data center applications. Our solution is also applicable to the fast-growing 5G and AI applications as well. eTopus was among the first to provide standalone SerDes interconnect solution with a monolithic, highly programmable SerDes for the emerging PAM4 standards. Our innovations in ADC/DSP-based physical layer transceiver technology deliver superior performance for Long Reach (high insertion loss channel) at low power consumption for next-generation converged Ethernet deployments.


eTopus is a VC-backed startup headquartered in Sunnyvale, California where all innovations and advanced architectures are developed. We have multiple locations in Hong Kong and Taiwan for design and customer support. Our investors include SK Telecom, HK-X, corporate VCs and cross-border funds.
