PCIe 5.0 SerDes PHY
The Rambus PCI Express (PCIe) 5.0 and Compute Express Link (CXL) PHY is a low-power, area-optimized, silicon IP core designed with a system-oriented approach to maximize flexibility and ease of integration. It delivers up to 32 GT/s data rates in performance-intensive applications for artificial intelligence (AI), data center, edge, 5G infrastructure and graphics. With the Rambus PCIe 5.0 controller core it comprises a complete PCIe 5.0 SerDes subsystem. Alternatively, it can be integrated with PIPE 5.2-compliant 3rd-party controllers. The PCIe 5 SerDes PHY supports PCIe 5.0, 4.0, 3.0 and 2.0, and has full support for manufacturability.
How PCIe 5.0 Works
The Rambus PCIe 5.0 PHY with the Expresso 5.0 digital controller comprise a high-performance serial link subsystem. Optimized for power in challenging, high-loss channels, our PCIe 5.0 interface solution is ideal for performance-intensive AI, data center, edge, 5G infrastructure and graphics applications.
The PHY consists of a PMA hard macro that supports PCIe 5.0, 4.0, 3.0 and 2.0 protocols and a physical coding sublayer (PCS) soft macro for PCIe that is PIPE 5.2 compliant. Co-verified with the PCIe 5.0 digital controller, the PHY can also be integrated with 3rd-party PIPE 5.2-compliant controllers.
