XAUI rate on UTP CAT 5 transmission experiment.



Hi XAUI specialists


Here is an 3.125 Gb/s 2^31-1 PRBS differential transmission example on a 2
meter 24AWG * 4 pair UTP cable used for ethernet connections. 
The specs on the cable says 100 MHz.

I cut off the connectors and applied SMA connectors for a differential pair.
THe other wires are used for GND on both ends.

GIGA lite CDR GD 41644 operates error free on this differential eye. 65
mVpp.

Removing the SDH filters and using 2*250 mVpp, the differential swing will
be 125 mVpp inner eye opening. 

Tomorrow, I will investigate the jitter tolerance on this system.
