The Tachyon DX2 HPFC-5400 is a highperformance PCI/PCI-X native dual 1 and 2 gigabit/sec Fibre Channel controller for host bus adapters and embedded subsystems. DX2 is the fourth member of the Agilent Technologies family of Fibre Channel interface controllers. It provides the performance enhancing features of PCI-X and is a single chip solution that offers the most economical component cost savings.

The DX2 HPFC-5400 interfaces directly to an industry standard PCI/PCI-X bus. Each channel can be independently configured to use either an HSPI-compatible 10-bit external SERDES or to use the internal SERDES.
