Diodes Incorporated PCIe Gen 2 Packet Switches

Diodes Incorporated PCIe Gen 2 Packet Switches deliver low-latency, low-power fully compliant (PCISIG 2.1 and 1.1) PCI Express Packet Switches. Diodes Incorporated PCIe Gen 2 Packet Switches enable high-speed serial point-to-point connections between multiple I/O devices and a root complex or microprocessor for optimized aggregation, fan-out or peer-to-peer communication of end-point traffic to the host. Ideal for industrial PC, networking, storage, and both mobile and desktop computers. They feature signal quality, system performance, flexibility, reliability, system timing, EMI, express cable, and much more.
