Abstract
A digital isolator includes a receiver configured to receive digital raw data at a primary side of the digital isolator. A digital-to-digital encoder is disposed at the primary side of the digital isolator. The digital-to-digital encoder is configured to create coded data. One or more digital isolators are configured to transmit the coded data across a transformer and an isolation barrier to create output coded data. A digital-to digital decoder is disposed at a secondary side of the digital isolator. The digital-to digital decoder is configured to decode the output coded data to create decoded data, determine error in coupling across the digital isolator based on the decoded data and the digital raw data, and provide an error signal based the error in coupling across the digital isolator.
