XIO3130 PCI Express 1:3 4-Port 4-Lane Switch Texas Instruments XIO3130 PCI Express 1:3 4-Port 4-Lane Switch is a PCI Express ×1 3-port fanout switch. The XIO3130 provides a single ×1 upstream port supporting full 250MB/s packet throughput in each direction simultaneously. Three independently configurable ×1 downstream ports are provided that also support full 250MB/s packet throughput in each direction simultaneously. A cut-through architecture is implemented to reduce the latency associated with packets moving through the PCI Express fabric. As soon as the address or routing information is decoded within the header of a packet entering an ingress port, the packet is directed to the egress port for forwarding. Packet poisoning, using the EDB framing signal, is supported in circumstances where packet errors are detected after the transmission of the egress packet begins.
