How 12G works
The Rambus 12 Gbps Multi-Protocol SerDes (MPS) PHYs are a general-purpose, high-speed serial link transceiver subsystem that support data rates from 1.25 Gbps to 12 Gbps. Optimized for power and area in high-loss channels, our 12G MPS PHYs are suitable for a broad range of enterprise-class systems.
The PHYs include a PMA hard macro that supports a broad range of networking protocols as well as a PCS-BIST soft macro for PCIe that is PIPE4 compliant. They have a minimal set of broadside control and is configurable in x2, x4 and x8 lane configurations. This gives the PHYs improved flexibility and support for a wide range of applications.
The 12G SerDes PHY utilizes transmit and receive equalization, data rate negotiation, and equalization adaptation to improve system margin and performance. This ensures that data is recovered even in the presence of channel and system interference.
Available on TSMC, Global Foundry, and Samsung process nodes.
