Components and Transceiver Interfaces

This section describes the starter board's communication ports and interface cards

relative to the Cyclone IV GX device. The starter board supports the following

communication ports:

■ PCI Express

■ 10/100/1000 Ethernet

■ Transceiver SMA connectors (optional)

PCI Express

The Cyclone IV GX Transceiver starter board fits entirely into a PC motherboard with

a ×1 PCI Express slot which can accommodate a half height low-profile PCI Express

add-in card. The starter board comes with a full height I/O bracket for its low profile

form factor card. This interface uses the Cyclone IV GX device's PCI Express hard IP

block, saving logic resources for the user logic application.

f For more information on using the PCI Express hard IP block, refer to the PCI Express

Compiler User Guide.
