Abstract
An embodiment of a communication system for transmitting and receiving data across an isolation barrier may include a communication circuit connected to an isolator at a first side of the isolation barrier, the communication circuit having a transmit circuit to drive a first data signal onto the isolator based on input data received by the communication circuit, a receive circuit to receive a second data signal from the isolator and produce output data based on the received second data signal, and a control circuit to control the transmit and receive circuits to provide time division multiplexing of the first and second data signals. The control circuit may transition to a transmit state in which the transmit circuit drives the first data signal onto the isolator from a receive state in which the receive circuit receives the second data signal from the isolator in response to detecting a condition as a function of receiving a predetermined number of bits of the second data signal and passage of a predetermined time period.
