A digital phase-locked loop includes a first clock divider, a decimation filter, a proportional integral filter, a signal conditioner, and a digitally controlled oscillator. The first clock divider divides a first clock signal including a first clock rate to generate a second clock signal including a second clock rate less than the first clock rate. The decimation filter converts an input signal at the first clock rate to an output signal at the second clock rate. The proportional integral filter filters the output signal at the second clock rate to generate a filtered output signal. The signal conditioner conditions the filtered output signal at the second clock rate to generate a conditioned output signal. The digitally controlled oscillator generates a carrier clock signal in response to the conditioned output signal.

A device includes: first and second electronic sides; an isolation barrier galvanically isolating the electronic sides from one another and including a signal coupler configured to enable signaling between the electronic sides over the isolation barrier via electromagnetic coupling; and transceiver circuitry included in both electronic sides and configured to implement, based on a frequency response profile of the isolation barrier, full-duplex communication between the electronic sides using the same signal coupler. According to another embodiment of a device, the device includes: electronic circuitry; an isolation barrier galvanically isolating the electronic circuitry and including a signal coupler configured to enable signaling over the isolation barrier via electromagnetic coupling; and transceiver circuitry configured to implement, based on a frequency response profile of the isolation barrier, full-duplex communication between the electronic circuitry of the device and electronic circuitry of another device using the same signal coupler.
