PCIe Crossover adapter board AB16-PCIeXOVR Manual Ver2.0E Introduction Thank you for choosing PCIe Crossover adapter board Part Number: AB16-PCIeXOVR (adapter board in this manual). This adapter board supports 1/4/8-lane PCIe (PC-Express) and converts between PCIe host and PCIe device, and can apply to FPGA evaluation board from Altera or Xililnx. The adapter board mounts two 8-lane PCIe socket connectors on both of component and solders side, and connects between TX pair and RX pair in each connector. Generally, PCIe card-edge connector on FPGA evaluation board is assigned as device function and can insert into PCIe socket of general PC so that FPGA can operate as a PCIe device. However, when FPGA evaluation board is connected to the component side socket of this adapter board and some PCIe device is connected to the solder side socket, FPGA with PCIe host function in its logic can communicate with connected PCIe device. So this board is ideal for PCIe host application development using FPGA evaluation board. This adapter board is also necessary when user evaluates NVMe-IP core from DesignGateway. The feature of the adapter board is as follows. Host side socket can accept general FPGA evaluation board with PCI-Express 8/4/1-lane. Device side socket can accept PCIe 8/4/1-lane device such as SSD. Mounts PCIe Low-jitter reference clock (HSCL differential signal, 100MHz default) source. Same PCIe clock is supplied to both host and device side. Side-band signal between host and device connection is configurable by jumper socket. 2.5V/3.3V power supply for side-band pin header for user original daughter board on the header. Flexible hardware reset with manual reset function for host and device reset usage. On-board On-Off power supply switch. 12V fan power connector for evaluation target NVMe SSD cooling via 12V fan.
