PHY for PCIe 7.0 and CXL

Overview

Most advanced PHY and controller IP for HPC, AI/ML, data communications, networking, and storage systems

Cadence® PHY IP for PCI Express® (PCIe®) 7.0 is a high-performance NRZ/PAM4 SerDes multi-protocol PHY that is PPA optimized for high-performance computing (HPC) and artificial intelligence and machine learning (AI/ML) applications. The ultra-long-reach equalization, robust clock-data recovery capabilities, low data path latency and low power consumption make it ideal for deployment in time-sensitive applications in HPC, AI/ML, data communications, networking, and storage systems. This multi-protocol PHY is highly versatile and scalable and can be configured to support X1, X2, X4, X8, and X16 lane widths with embedded bifurcation capability that allows multiple PCIe links of various link widths to co-exist and operate independently in the same macro.
