Title: Cable characteristic; pre-emphasis, post equalizer
Post by raymond_luo2003 on Apr 7^th, 2005, 3:46am

Dear all

I need your help regarding on cable characteristic. Does anyone implement pre-emphasis and post equalizer in USB (or other SerDes Gigabit Ethernet or 1394B) transmitter and receiver respectively? If yes, what's the cable characteristic of short co-axial cable, say 5 meters or 10 meters? What's the simulation model for the PCB trace and cable? What's the pre-emphasis and post equalizer structure built in that SerDes transiver?

Thank in advance,
Raymond
