The FWBX2-PCIE1xE220 is a Dual OHCI 1.2 Compliant FireWire 800 (IEEE 1394b) to PCI Express Host Adapter.
FWBX2-PCIE1xE220 is designed with Two key components.
3-Lane, 3-Port PCI Express Switch.
OHCI 1.2 Compliant IEEE 1394b Single Chip Host Controller.
Utilizing the standard PCI Express Switch, the 3-Lane/3-Port PCI Express Switch provides the most efficient fan-out solution for integrating two OHCI 1.2 Compliant IEEE 1394b Single Chip Host controllers into a small board design. Each OHCI 1.2 Compliant IEEE 1394b Single Chip Host controller takes advantages of 2.5 Gbps burst rate of 1-lane PCI Express bus in both directions and is fully compliant with PCI Express Base specification 1.1. This solution provides full PCI Express and 1394b functionality and performance.
