The next few slides will present specific examples of how the Cyclone® IV GX transceiver architecture can allow the user to implement multiple protocols efficiently. PCI express and Ethernet, specifically gigabit Ethernet, are ubiquitous these days. A simple design requiring a PCI express interface and an Ethernet connection can be implemented in as little as two channels. In a larger system, a multi-lane PCI express channel with channel bonding and multiple gigabit Ethernet channels could be implemented in a single quad due to the clocking flexibility.
