XIO3130 EVM
The Texas Instruments XIO3130 EVM is a functional implementation of a four-port PCIe-to-PCIe switch.
The XIO3130 EVM was designed to allow validation of three separate functional modes. In normal mode,
the EVM is configured as a generic PCI Express (PCIe) switch. In hot-plug mode, downstream ports 1 and
2 are configured as hot-pluggable slots. In ExpressCard mode, all three downstream ports are configured
to support the ExpressCard adapter board. The different functional modes are discussed later in this
document.
Figure 1-1
shows the EVM board. There are various jumpers, dipswitches, push buttons, and LEDs to
support the various functional modes. For the board to operate, power must be applied via the peripheral
power connector located to the right side of the board. Endpoints can be plugged directly into any one or
all of the downstream ports. The upstream edge connector can be plugged into any PCIe slot on a
motherboard. Once the EVM with attached endpoints is plugged into a PCIe motherboard and power is
provided to the EVM, nothing else needs to be done in order for the EVM to operate. The two LEDs in the
upper right-hand corner light up when power is applied to the peripheral power connector.
