The Technobox 4876 PCI Express to XMC
Adapter is a development/diagnostics tool that permits the testing of a PCIe card in an XMC site. Up to 8 lanes
are supported via the P15 connector. Several activity LEDs located at the edge of the board give an indication
of key XMC and PCI Express signals and voltages. The JTAG signals from the XMC bus and the PCI express bus are brought
out to headers allowing users the option of connecting the PCI express JTAG port to the PMC JTAG port or connecting JTAG
devices to either port. The I2C signals for both buses are brought to the same headers.
