摘要： Isolation circuits for digital communications and methods to provide isolation for digital communications are disclosed. An example isolation circuit includes an isolation barrier, a burst encoder in a first circuit, and an edge pattern detector in a second circuit. The example isolation barrier electrically isolates the first circuit from the second circuit. The example burst encoder generates a first pattern in response to receiving a rising edge on an input signal and generates a second pattern in response to receiving a falling edge on the input signal. The example edge pattern detector detects the first pattern or the second pattern received from the burst encoder via the isolation barrier, sets an output signal at a first signal level in response to detecting the first pattern, and sets the output signal at a second signal level in response to detecting the second pattern.
