PCIe Switch for USB4 Hubs, Hosts and Devices
Rambus PCIe Multi-port Switch for USB4 is a customizable, embedded Switch for PCI Express (PCIe) designed for implementations in USB4 devices. A fully configurable fanout switch, it provides one upstream port and up to 31 downstream ports. Rambus PCIe Multi-port Switch for USB4 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. Rambus PCIe Multi-port Switch for USB4 provides a flexible, scalable and configurable PCIe switching solution for USB4 Hubs, Hosts and Devices.
