PCI Express

With PHYs, Bridges, Switches, and End-points, TI offers an ever-growing selection of PCI Express® devices.

PCI Express provides a significant increase in available bandwidth (500 MBps per lane -- dual-simplex) without requiring the system integrator to use more expensive PCB materials or to add layers to accommodate wider parallel buses.

Each PCI Express lane supports 2.5 Gbps in each direction and can scale to support as many as 32 lanes in a single link. Low-cost platforms can now provide enough bandwidth in the I/O backbone to support applications like SATA, Gigabit/10-Gbit Ethernet and 1394b. PCI Express provides new features that will eventually enable true quality of service (QoS) for isochronous applications even in heavily loaded platforms.

Not only will PCI Express replace PCI, PCI-X and AGP where they exist in computing platforms today, but a number of revolutionary form factors and connectors will enable entirely new application spaces. The ExpressCard standard authored by PCMCIA will ultimately replace the CardBus slot as the most common aftermarket I/O expansion slot for notebooks and sealed-box desktop PCs. ExpressCard enables external sealed-card expansion for both PCI Express and USB 2.0 peripherals. In addition, the PCISIG is developing a highly anticipated PCI Express cable standard that will allow system designers to seamlessly provide generic I/O connectivity outside of the box for exciting new concepts like the split-chassis PC.
