SCPU024 Overview The XIO2200 Evaluation Board (EVM) is a functional implementation of a PCI Express to Two- Port 1394a OHCI controller using the Texas Instruments XIO2200 PCI Express to PCI Bus Translation Bridge with 1394a OHCI and Two-Port PHY. Designed as a x1 add-in card, it is routed on FR4 as a standard 4-layer (2 signal, 1 power, 1 ground) board with a 100-Ω...
SCPU024 1394a Connectors The XIO2200 EVM provides 2 standard 1394a connectors. 12 V is provided to the connectors so that bus powered peripherals may be used although fuses limit the amount of current that may be drawn to 1 A per each port. Also see section 2.4 on the external power connector for further information of power limitations.
SCPU024 LEDs The XIO2200 EVM has LEDs on board to indicate availability of power and status of certain control signals. The onboard LEDs are as follows D1 – 1.5V (note: this LED will generally not light due to absence of LED with Vf <= 1.5V) D2 –...
What to do if EVM is not working 3.4.1 Check 1.5-V Power. The XIO2200 requires 1.5 V for proper operation. As this voltage is not provided from the PCI Express connector it is regulated from 3.3 V from the connector.

Once the bridge is communicating with the system, BIOS and/or the OS are expected to configure the bridge in order for proper operation. As the XIO2200 appears to software to be a standard PCI to PCI Bridge with a PCI based 1394 controller behind it, most existing BIOS and OS should be capable of configuring the bridge and controller with no special considerations for PCI Express.
