Networking systems are becoming increasingly complex. Meeting the power, performance and density requirements of advanced networking-class ASICs is a significant challenge for system OEMs. Next-generation 12.8, 25.6 and 51.2Tb/s switches and routers demand extreme flexibility in system architecture, greater I/O bandwidth and power scaling to achieve the required performance and density.
Key challenges facing network architects are:
The SerDes family is a critical piece of eSilicon’s 7nm IP platform that provides a complete ecosystem of networking-optimized, highly configurable IP. All of the IP in the platform is “plug and play,” using the same metal stack, reliability requirements, operating ranges, control interfaces and DFT methodology. This configurability and compatibility results in better performance, higher density and faster time to market.
At the core of the 7nm IP platform is eSilicon’s SerDes technology which delivers a new level of performance and versatility and is based on a novel DSP-based architecture. Two 7nm PHYs support 56G and 112G NRZ/PAM4 operation to provide the best power efficiency for server, switches and routers. The architecture delivers unprecedented power efficiency for a true long-reach capability, with hole-free operation down to 1Gb/s. The clocking architecture provides extreme flexibility to support multi-link and multi-rate operations per SerDes lane. A multitude of protocols are supported including a variety of Ethernet standards and Fibre Channel. The architecture also allows further reductions in power consumption for shorter-reach channels.
Our new SerDes family was developed by a world-class SerDes team with over 12 years of proven experience in networking, including two 28nm silicon-proven 56G SerDes implementations. The new SerDes family leverages the same architecture plus some unique features derived from eSilicon’s long-standing experience integrating complex SerDes into bleeding-edge networking ASICs.
Silicon-proven SerDes architecture
In addition to outstanding performance and versatility, eSilicon’s SerDes family provides a new level of user experience for the ASIC design and signal integrity communities. Leveraging a decade of experience integrating complex SerDes into networking ASICs, eSilicon incorporated this unique knowledge into its new 7nm SerDes family. The result is a new-to-the-market, customer-centric SerDes that is easy to integrate and easy to use.
