Hello, 
Could you please tell me the coding (when unknown) and max data frequency 
(for a pattern "1010101010") for the Ethernet standards listed below: 
For exemple, a serdes link with 1Gbps NRZ coding has a max data frequency 
of 500MHz. 

 * Ethernet 10Base-T            Manchester coding       Max data freq: ?
 * Ethernet 100Base-TX          MLT3 coding             Max data freq: ?
 * Ethernet 100Base-EFX NRZI coding             Max data freq: ?
 * Ethernet 1000Base-T          ? coding                Max data freq on 
one 250 Mbps pair: ?
