SGMII Interface
in [FPGA]

From: Jeremy Stringer on 13 Dec 2005 18:46 Not quite on topic - but I thought somebody here might know - Does anybody know where I can get hold of the SGMII spec (Used on SFP modules, esp. 10/100/1000 copper)? All I can find in the SFP/PHY datasheets that I've looked at so far is references to the data bytes being repeated 10 times (Which doesn't help much with autonegotiation). Thanks, Jeremy

To get the spec, you have to either have a subscription or have access to a company that does ;) Cheers PeteS
