Claim 13:
14. A method of operating a system having circuitry on a first side of an isolation barrier and circuitry on a second side of the isolation barrier, the method comprising:
receiving data at the first side from the second side, wherein the first side includes a trimmed oscillator and the second side includes a tunable oscillator;
counting a number of faults in the data at the first side;
responsive to the number of faults reaching a predetermined threshold, transmitting a training sequence from the first side to the second side;
tuning the tunable oscillator based on the training sequence;
transmitting a data signal from the second side to the first side of the isolation barrier; and
responsive to the first side successfully decoding the data signal, transmitting a data sequence to the second side.
