Abstract:
In a general aspect, a data communication circuit can include a differential transmitter configured to be coupled with a differential input of a first unidirectional differential isolation channel, and a differential receiver configured to be coupled with a differential output of a second unidirectional differential isolation channel. The differential receiver can include a comparator that has a threshold that is adjustable based on a signal received via the second unidirectional differential isolation channel.
