10 Gigabit to 1 Gigabit Ethernet Converter for XAUI20 (XG2G20)

Features

• Converts between XGMII and GMII interfaces to allow a 10 Gigabit Ethernet MAC to operate in a Gigabit environment
• Converts between XGMII and MII interfaces to allow a 10 Gigabit Ethernet MAC to operate in a 10/100M environment
• Interfaces to de-multiplexed IEEE802.3 XGMII (uses 64 bit wide data sampled on single clock edge rather than 32 bit wide data sampled on both edges of the clock)
• Interfaces to double data width GMII clocked at 62.5MHz as provided by the Cadence XAUI20 IP core when configured for gigabit operation
• Supports gigabit operation through 1000BASE-X or SGMII when connected to the Cadence XAUI20 IP core
• Supports 100 Megabit SGMII operation (where every data byte is repeated ten times) when used in conjunction with the Cadence XAUI20 IP core
• Supports transport of 802.3az (EEE) low power idle indication

Deliverables

• Synthesizable Verilog RTL
• Verilog testbench and scenarios
