The PCI Express interface supports a channel width of ×1 as well as the connection
speed of Gen1 at 2.5 Gbps/lane.

The board’s power can be sourced entirely from the PCI Express edge connector when
installed into a PC motherboard. Turn the power switch (SW1) to

ON

position when

you install the board into a PC motherboard. Although the board can also be powered
by a laptop power supply for use on a lab bench, it is not recommended to use from
both supplies at the same time. Ideal diode power sharing devices have been
designed into this board to prevent damages or back-current from one supply to the
other.

The

PCIE_REFCLK_P

and

PCIE_REFCLK_N

signals are a 100-MHz differential input

that is driven from the PC motherboard on this board through the PCI Express edge
connector. This signal connects directly to a Cyclone IV GX

REFCLK

input pin pair.

This clock is terminated on the motherboard and therefore, no on-board termination is
required. This clock can have spread-spectrum properties that change its period
between 9.847 ps to 10.203 ps. The I/O standard is High-Speed Current Steering Logic
(HCSL).

By default, the

GXB_RX0

channel of the FPGA is connected to the

PCIE_RX_P

and

PCIE_RX_N

signals, while the

GXB_TX0

channel is connected to the

PCIE_TX_P

and

PCIE_TX_N

signals.

Table 2–24

summarizes the PCI Express pin assignments. The signal names and

directions are relative to the Cyclone IV GX FPGA.
