Other Parts Discussed in Thread: ISO7341C
I would like to know the carrier frequency used in ISO7841 and similar digital isolators. This relates to some issues we encounter with close proximity GSM antenna transmissions, that possibly corrupts isolated I2C communication (isolated via ISO7841). Immunity problems occurs when working on 2G 900MHz band and in weak GSM signal strength conditions (the GSM bursts have up to 2W of power in such situation). If you have some other useful information regarding this ISOxxxx family isolators and its immunity to high frequency interference please share.
