Abstract

See full text

In an example, a system includes circuitry on a first side of an isolation barrier and circuitry on a second side of the isolation barrier, where the isolation barrier is operable to electrically isolate the first side from the second side. The system also includes a trimmed oscillator, a first transmitter, and a first receiver on the first side, the trimmed oscillator coupled to the first transmitter. The system includes a tunable oscillator, a second transmitter, and a second receiver on the second side, the tunable oscillator coupled to the second receiver and the second transmitter. In the system, the first side is configured to transmit a training sequence to the second side, and the second side is configured to tune the tunable oscillator based on the training sequence.
