The DIODES PI7C9X3G606GP is a PCIe GEN3 packet switch that supports 6 lanes of GEN3 SERDES in flexible 3- port, 5-port and 6-port configurations. The architecture of the PCIe packet switch allows the flexible port configuration by allocating variable lane widths for each port. The packet switch can be configured to have different port types such as upstream port, downstream ports and Cross-Domain End-Point (CDEP) ports to support various applications, which include port fan-out, dual-host connectivity. Inside the packet switch, multiple DMA channels are embedded to facilitate data communication more efficiently among host(s) and end-points.
