Product InformationDescriptionThe XIO2200A Evaluation Board (EVM) is a functional implementation of a PCI Express to Two-Port 1394a OHCI controller using the Texas Instruments XIO2200A PCI Express to PCI Bus Translation Bridge with 1394a OHCI and Two-Port PHY. Designed as an x1 add-in card, it is routed on FR4 as a standard 4-layer (2 signal, 1 power, 1 ground) boardwith a 100-Ω differential impedance (for PCI-Express pairs), 110-Ω differential impedance (for 1394a pairs), and 50-Ω single-ended impedance using routing guidelines and requirements specified in the PCI Express Card Electromechanical Specification rev 1.0a, PCI Local Bus Specification rev 2.3, and IEEE 1394--1995 Specification. All board power for the XIO2200A EVM and any bus power provided to the 1394 connectors are provided or derived from the standard voltages provided on the PCI-Express connector. However due to the limited availability of 12-V current (for 1394 bus power) an option has been provided to power 12-V rail from an external 4-pin floppy drive connector if testing bus-powered 1394a devices which require more than the 500 mA that can be drawn (by specification) from the PCI Express x1 Connector.
