This paper will discuss the various challenges of designing high speed SerDes, as well as the importance of detailed modeling and design of highly programmable circuits and debug interfaces.
The Rambus 56 Gbps Multi-Protocol SerDes (MPS) PHYs are a PAM-4 and NRZ compliant IP solutions that provide reliable performance across challenging long-reach data center environments.
HBM is a high-performance memory that features reduced power consumption and a small form factor. It combines 2.5D packaging with a wider interface at a lower clock speed (as compared to DDR4) to deliver higher overall throughput at a higher bandwidth-per-watt efficiency for high-performance computing applications.
The Rambus 28 Gbps Multi-Protocol SerDes (MPS) PHYs are comprehensive IP solutions that deliver enterprise-class performance across the challenging signaling environments typical of networking and server systems. With high performance and multi-protocol compatibility, the PHYs support data rates from 1.25Gbps to 28.1Gbps across copper and backplane channels with more than 30dB channel insertion loss in a wide range of industry-standard interconnect protocols. They feature application-specific optimization enabled by an efficient and scalable architecture with adaptive and programmable receive equalization, and support for transmit FIR adaptation.
The Rambus DDR4 memory PHY delivers industry-leading data rates of up to 3200 Mbps and is compatible with JEDEC standard DDR4, and DDR3. Designed to meet the needs of the most demanding networking and data center applications, the silicon-proven PHY combines performance and power efficiency with superior design flexibility to provide customers with a differentiated and easy to integrate solution.
