Thanks Alan. Actually, I did a fair bit of research into what's available at the moment. I have my PD (powered device) chip samples already, I will design a board when I get the chance. Maxim has a super cool single channel PSE (power sourcing equipment) chip. Most of the other manufacturers only make a quad device minimum, which is great if you're building a hub, but not so great if you just want to make a single channel mid stream power inserter. Unfortunatly, that chip won't be available for samples or purchase until January I believe. Ah well...at the moment I can wait! Josh "Alan B.
