1. A method for calibrating an isolator device, the method comprising:
configuring the isolator device to enter a diagnostic mode;
receiving a calibration signal on a differential pair of nodes of a programmable receiver signal path of a first integrated circuit die of the isolator device, the calibration signal transmitted across an isolation channel;
generating a digital diagnostic signal corresponding to an amplitude of the calibration signal; and
configuring the programmable receiver signal path based on the digital diagnostic signal, the digital diagnostic signal being indicative of mismatch of the isolation channel, the isolation channel being coupled between a differential pair of receiver nodes of the first integrated circuit die and a differential pair of transmitter nodes of a second integrated circuit die of the isolator device.
