PCI Express Lane
One PCI Express Lane is a set of 4 signals that contains two differential lines for transmitting and two differential lines for Receiving. Clocking information is embedded
into the data stream.
x1, x2, x4, x8, x16
x1 refers to one PCI Express Lane of basic bandwidth; x2 to a collection of two PCI Express Lanes; etc.. Also referred to as x1, x2, x4, x8, or x16 link.
PCI Express Mini Card PCI Express Mini Card add-in card is a small size unique form factor optimized for mobile computing platforms.
