PCI EXPRESS® CARD EDGE CONNECTORS
DESCRIPTION
These pitch, vertical card edge
connectors are used to implement PCI Express®
architecture in desktop PCs, workstations, and
servers. The base connector family offers one
to 16 high-speed serial PCI Express Lanes.
Each serial lane supports Gb/s (per
direction) in a 100Ω Gen1 system or Gb/s
in a Gen2 system with an 85Ω differential
environment.
The base connector family supports x1, x4, x8,
or x16 link widths to suit different bandwidth
requirements. The 36-position, basic bandwidth
(x1) version supports a single PCI Express Lane
and could be used as the replacement for the
PCI connector. The 164-position, high band-
width version will support 16 PCI Express Lanes
and will be used for applications that require
higher bandwidth, such as graphics. The x4
and x8 connectors provide 64 and 98 contacts,
respectively. All connectors support the PCI
Express signal and power requirements, as
well as auxiliary signals at the interface between
system board and add-in card hardware.
Staggering the edge fingers by on the
add-in card provides sequential mating for hot
plug capability.
