All I/O channels operate as a unified mix matrix under the PCI-424 card's powerful CueMix DSP mixing engine.
Unlike older parallel technologies, PCI Express guarantees each
device dedicated bandwidth to and from the system controller. PCI
Express cards and slots are defined by their bandwidth, or number of
data lanes — typically one lane, four lanes, eight lanes, or 16 lanes.
At 250 MBps per lane, a four-lane slot can transfer data at up to 1
GBps and an eight-lane slot, up to 2 GBps — almost twice as fast as a
133MHz PCI-X slot at a maximum throughput of just over 1 GBps. The new
PCIe-424 card can be installed in any PCI Express slot (regardless of
its number of lanes). PCI Express delivers more than enough bus
bandwidth for the 424 card, while ensuring that other PCI devices won't
"steal" bus cycles from the 424 card.
