1. An isolator product comprising:
a first integrated circuit die;
a second integrated circuit die; and
an isolation channel, the first integrated circuit die including a transmitter circuit configured to transmit a calibration signal to the second integrated circuit die via the isolation channel, the calibration signal having a first frequency during a first interval and having a second frequency during a second interval that does not overlap with the first interval, the first frequency and the second frequency straddling a frequency of a carrier signal used by the first integrated circuit die to transmit data to the first integrated circuit die via the isolation channel.
