The Altera
®
Low Latency (LL) Ethernet 10G (10GbE) Media Access Controller (MAC) IP core is a
configurable component that implements the IEEE 802.3-2008 specification. The MAC IP core offers the
following operating modes:
• 10G—single-speed mode that implements the Avalon
®
Streaming (Avalon-ST) interface on the client
side and the 32-bit single data rate (32-bit SDR) XGMII on the network side.
• 1G/10G—dual-speed mode that implements the Avalon-ST interface on the client side and GMII/32-
bit SDR XGMII on the network side.
• 10M/100M/1G/10G—quad-speed mode that implements the Avalon-ST interface on the client side
and MII/GMII/32-bit SDR XGMII on the network side.
To build a complete Ethernet subsystem in an Altera device and connect it to an external device, you can
use the LL Ethernet 10G MAC IP core with an Altera PHY IP core such as a soft XAUI PHY or any of the
supported PHYs.
The following figure shows a system with the LL Ethernet 10G MAC IP core.
