Altera Triple Speed Ethernet MegaCore Function - Manual (Page 14)

• MDIO access
• Frame transmission and error handling
• Frame reception and error handling
• Ethernet frame MAC address filtering
• Flow control
• Retransmission in half-duplex
Altera has also validated the Triple-Speed Ethernet MegaCore function in both optical and copper platforms
using the following development kits:
• Altera Nios II Development Kit, Cyclone II Edition (2C35)
• Altera Stratix III FPGA Development Kit
• Altera Stratix IV FPGA Development Kit
• Quad 10/100/1000 Marvell PHY
• MorethanIP 10/100 and 10/100/1000 Ethernet PHY Daughtercards
Optical Platform
In the optical platform, the 10/100/1000 Mbps Ethernet MAC, 1000BASE-X/SGMII PCS, and PMA functions
are instantiated.
The FPGA application implements the Ethernet MAC, the 1000BASE-X PCS, and an internal system using
Ethernet connectivity. This internal system retrieves all frames received by the MAC function and returns
them to the sender by manipulating the MAC address fields, thus implementing a loopback. A direct
connection to an optical module is provided through an external SFP optical module. Certified 1.25 GBaud
optical SFP transceivers are Finisar 1000BASE-SX FTLF8519P2BNL, Finisar 1000BASE-LX FTRJ-1319-3,
and Avago Technologies AFBR-5710Z.
Copper Platform
In the copper platform, Altera tested the Triple-Speed Ethernet MegaCore function with an external
1000BASE-T PHY devices. The MegaCore function is connected to the external PHY device using MII,
GMII, RGMII, and SGMII, in conjunction with the 1000BASE-X/SGMII PCS and PMA functions.
A 10/100/1000 Mbps Ethernet MAC and an internal system are implemented in the FPGA. The internal
system retrieves all frames received by the MAC function and returns them to the sender by manipulating
the MAC address fields, thus implementing a loopback. A direct connection to an Ethernet link is provided
through a combined MII to an external PHY module. Certified 1.25 GBaud copper SFP transceivers are
Finisar FCMJ-8521-3, Methode DM7041, and Avago Technologies ABCU-5700RZ.
Performance and Resource Utilization
In the following tables, the f
MAX
of the configurations is more than 125 MHz.
