I'm using an ADM 2587 with the recomended schematic .
Now we had some Problems to get the Device through the IEC 61000-4-6 Test (Radio frequency / Common mode).
10V of HF will be induced in the COM Lines at this test . Between 550khz and 1,5 Mhz the Communication fails.
It seems that the ADM will cut the Level of HF at 9-10V and so the Signal get's unsymetrical and so the Comunication fails.
Are there anyone with similar Problems ?
