eTopus is an innovator and technology leader of high performance, mixed-signal, ultra-high speed semiconductor interconnect solutions.
eTopus pioneered the ADC-based DSP system architecture for ultra-high speed wireline applications. The innovative architecture, which delivers superior Bit Error Rate performance for 1-112G PAM-4 SerDes IP, has been proven over multiple generations of silicon and has been adopted by Tier-1 networking, storage, and 5G OEMs. Founded in 2014, eTopus has a world-class innovation team with a track record of inventing multiple industry firsts involving mixed signal circuits with complex DSP algorithms over nearly 25 years. eTopus currently holds 10 US patents from system algorithm to circuit implementation related to the ADC/DSP-based SerDes.
eTopus has built from the ground up an advanced system architecture to deliver superior Bit Error Rate (BER) performance for Long Reach applications. The advanced architecture developed is called eTopus Partial-Response Technology (ePRTTM) architecture. It is a highly programmable and adaptive Receiver DSP architecture, and fully compatible with existing standards. This innovative architecture is proven with multiple generations of silicon and was tested extensively and collaboratively with our lead customers for performance, robustness, standard compliance, and interoperability.
The innovative architecture utilizing advanced DSP techniques demonstrated excellent scalability over data rates and insertion losses, superior reliability, and extreme CDR robustness over a wide range of PVT.
The Company product family is called ePHY™. The ePHY product line features a scalable system architecture that supports a wide range of data rates and wide range of insertion losses. eTopus partners with the customers to map and co-optimize our scalable architecture to the applications of our customers’ vertical market. Our Software Development Kit (SDK) includes a comprehensive set of APIs to demystify SerDes bring-up and application deployment through our proprietary algorithms implemented in the firmware.
