Abstract
An isolator system has an isolator that generates differential isolator signals and a receiver that generates digital data representative of signals received from the isolator. The system also may include an RC filter coupled between the isolator and the receiver. During operation, the filter may distribute transient signals across various circuit paths in the isolator, only some of which are coupled to the receiver inputs. Over time, the filter may attenuate transient contributions at the receiver inputs. In this manner, the filter may limit effects of these common mode transients.
