PCIe Switch for USB4

The PCIe Switch for USB4 (formerly XpressSWITCH) is a customizable, embedded switch for PCI Express (PCIe) designed for implementations in USB4 devices.

How the PCIe Switch for USB4 Works

A fully configurable fanout switch, the PCIe Switch for USB4 provides one upstream port and up to 31 downstream ports. It enables designers to support tunneling of PCIe traffic in USB4 Hubs as mandated by the USB4 specification, and is also an ideal addition to USB4 Devices or Hosts for attaching internal or external PCIe devices.

By implementing internal PCIe devices, designers can differentiate their USB4 ICs while reducing latency and power consumption. The PCIe Switch for USB4 provides a flexible, scalable and configurable PCIe switching solution for USB4 Hubs, Hosts and Devices.

The PCI Express® (PCIe®) interface is the critical backbone that moves data at high bandwidth and low latency between various compute nodes such as CPUs, GPUs, FPGAs, and workload-specific accelerators. With the rapid rise in bandwidth demands of advanced workloads such as AI/ML training, PCIe 6.1 jumps signaling to 64 GT/s with some of the biggest changes yet in the standard.
