Abstract
A digital isolator module for high level common mode transient immunity is provided, comprising a transmitter circuit (TX), a receiver circuit (RX) and an isolation barrier which is connected there in between, wherein the transmitter circuit is electrically connected to a first ground voltage level and the receiver circuit is electrically connected to a second ground voltage level. The receiver circuit further comprises a resistance set, a high speed detector and a demodulator. By employing the proposed circuit diagram of the invention, interferences occurring at the common mode are suppressed and an RX output signal is synchronized with its input signal without having propagation delay.
