High speed data links play a key role in industrial and medical systems. Galvanic isolation in high-speed links ensures the safety of human operators and instruments. Optoisolators generally achieve high voltage ratings but suffer from delay and reliability concerns [1]. A mm-wave isolator [2] using fiber can transmit 4Gb/s data but it adds system complexity. In contrast, magnetically and capacitively coupled digital isolators are a more compact solution. Conventional digital isolators can tolerate >10kV surge voltage and >50kV/µs common-mode transient (CMT) across a high-voltage-rated dielectric thin film [3-6]. However, their data rate is limited to 0.5Gb/s except for [4], which runs at 2.5Gb/s. To provide isolated solutions for protocols like USB3 and HDMI, isolator data rates must be increased to 10Gb/s. However, doing this in the presence of CMT strikes is challenging because CMT currents can couple through the parasitic
