Abstract
Methods and apparatus embodiments to communicate data via a digital isolator by receiving an input data stream having first and second states, generating a first pulse train for the first state and a second pulse train for the second state. The first and second pulse types are transmitted across a voltage barrier of a digital signal isolator and received by a receive channel. The first and second pulse trains are processed to recover the input data stream in an output data stream. Data/System integrity functionality can identify fault conditions from an alteration of transmitted pulses.
