Hi. I need to connect an embedded computer to a host through a high speed link. The embedded computer will be at the same floating ground as circuitry connected to a patient. So I need 4KV AC isolation from mains supply ground and other I/O. I do not have much experience with network circuitry though. NIC isolation transformers usually guarantee
1500Vac isolation. I would appreciate having suggestions on parts that could meet my requirements or alternative ways to connect this hardware with a computer.TIA.
