PCI Express® Standard Interconnects

PCI Express® Standard Interconnects

PCI Express® is an I/O interconnect bus standard that expands the data transfer rates of original PCI™.


FAMILY OVERVIEW

PCI Express®

PCI Express® (PCIe®) is a high-speed PC I/O bus standard (which includes a protocol and a layered architecture) that replaces legacy PCI, PCI-X and other bus standards. PCIe® enhancements include high data rates, lower I/O count and smaller footprints. PCI Express® is a two-way, serial connection that carries data in packets along multiple pairs of point-to-point data lanes. This contrasts with the single parallel data bus of traditional PCI that routes data at a set rate.

Initial bit rates for PCI Express® Generation 1 reach 2.5 Gbps per lane direction, which equate to data transfer rates of approximately 200 Mbps.

PCI Express® Generation 2 supports data rates up to 5 Gbps, while PCI Express® Generation 3 supports data rates up to 8 Gbps.

PCI Express® was developed so that high-speed interconnects such as 1394b, USB 2.0, InfiniBand™, and Gigabit Ethernet would have an I/O architecture suitable for their transfer high speeds. Samtec offers products that meet the PCI Express® form factor as well as connectors and cable assemblies that are capable of PCI Express® Gen 1, Gen 2 and Gen 3 data rates.
