As the leading provider of 10 Gbps Ethernet (10GbE) for FPGA devices, Altera offers the XAUI PHY MegaCore® function intellectual property (IP) core for you to easily build systems with a very high throughput Ethernet connection. This XAUI PHY along with a 10GbE media access control (MAC) IP core enables an Altera® device to interface to a 10GbE network through a variety of external devices, including a 10GbE PHY device or optical transceiver module.
You can implement the XAUI PHY (excluding the PHY management functions) in hard silicon in Altera Stratix® IV (GX and GT), Stratix II GX, Arria® II GX, and Cyclone® IV GX FPGAs with serial transceivers faster than 3 Gbps. The PHY management functions are implemented in soft IP. XAUI PHY can also be implemented in soft IP form in Stratix® V , Stratix IV, Arria V, and Cyclone V FPGAs with serial transceivers. Additionally, for applications requiring 20 Gbps throughput, Altera's XAUI PHY solution can support DXAUI (4x 6.25 Gbps) implementations on Stratix IV (GX and GT) FPGAs. Figure 1 illustrates an example of XAUI PHY in Altera devices.
