Overview

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.

How a 16Gbps Multi-link, Multi-protocol SerDes PHY Can Transform Datacenter Connectivity

Increasingly, more of the focus on mobile has centered around cloud datacenters and the networking to get the data back and forth between these datacenters and the mobile device. Functions like voice recognition and mapping depend on the ability to split the functionality between the smartphone, for local processing like encryption and compression, and the back end, where a large number of servers can do the heavier lifting before returning the results.

One PHY, Zero Tradeoffs: Multi-Protocol PHY for Edge AI Interface Consolidation

The Cadence 10G multi-protocol PHY was architected to address this exact challenge. Designed to scale across multiple process nodes, it consolidates PCI Express (PCIe), USB, DisplayPort, Ethernet, and other interfaces into a single, compact, silicon-efficient block. What sets it apart is simultaneous multi-protocol support, which enables multiple data paths without duplicating hardware, requiring extra board connectors, or paying the area and power penalty of separate IP blocks.

Rethinking Edge AI Interconnects: Why Multi-Protocol Is the New Standard

Modern compute systems have evolved beyond reliance on a single dominant interface. Today, they're increasingly defined by their ability to support multiple high-speed protocols concurrently—including PCIe, Ethernet, and others. This shift toward multi-protocol capability is fundamentally reshaping how we architect intelligent edge AI systems, especially as inferencing workloads grow more distributed, data-intensive, and latency-sensitive.
