There is a problem: my customer has replaced ADUM1201A with ISO7221AD, after that the scheme stopped working. The speed is 512kbit/s - two times slower than the maximum in datasheet. There are no problems on lower speeds - 90kbps, 12kbps. What could be the problem?

the problem could be noise pulses due to a fault in the filter design in the A-version.

thank you,
Thomas
