That's great detail, thanks for looking that up. The 200Khz wave may not be a big deal, but when you start getting strong harmonics then things really go south

Once on a capacitive screen controller design I had to stick in some pseudo-randomization on the electrode PWM to avoid this coupling. It was a pain in the ass.
