How Rambus PCIe 4.0 SerDes PHY Works
The Rambus PCIe 4.0 SerDes PHY is a high-performance serial link subsystem. Optimized for power in challenging, high-loss channels, our PCIe 4.0 PHYs are ideal for networking, storage and data center systems.
The PHYs come complete with a PMA hard macro that supports PCIe 4.0, 3.0, and 2.0 protocols and a physical coding sublayer (PCS) soft macro for PCIe that is PIPE4.2 compliant. They have a minimal set of broadside control and are configurable in x2, x4 and x8 lane configurations. This gives the PHYs improved flexibility and support for a wide range of applications. The PCIe 4.0 PHYs are rigorously tested through third party compliance testing and internal interoperability system testing.
