My gut tells me that the very poor low frequency response of the=20 Ethernet transformers will degrade the AES signal. But I haven't=20 actually tried it to find out. I should do so - we build AES isolation cards for a customer and we=20 do have a nice AES test setup here. dwayne At 08:30 PM 6/17/2015, Harold Hallikainen wrote: >Since it's fairly common to run AES3 on CAT5 cable and use RJ45 >connectors, the next step is to consider the use of Ethernet magnetics for >AES3.
