Also forgot to mention logic level conversion.  Convert 1.8v logic to 3.3v, & 5v, and 
back...

  Subject: [PEDA] Data line transformers (was: Antenna coil)


  My first test PCB printed with data line transformers is coming next month, no 
electrical connection from A side to B side.  Is anybody interested?

  Capabilities:
  Get over 500 megabits from 1 side to the other.
  Perfect phase clock drivers & inverters.

  Great for isolating SPDIF/AC3/DTS audio signals, Ethernet line transformers, cheaper 
& smaller than optocouplers, faster by a long shot, analog signal mixers and more...

  Slow speed signals need only a 2 layer PCB, high speed need 4 layer.  Also, 1 PCB to 
the next with gap sizes typically under .2 inch. (this is for super high voltage 
separation, in the 5-50KV and above when PCBs edges are coated.)
