The clock frequency isn’t the issue, rather the rise time of the signal edges. You can have a 1 kHz clock with GHz of bandwidth.
Case in point are switching power supply ICs, specifically ones with integrated switches. A 200 kHz switcher can radiate noise past 2 GHz due to the fast rise time of the input switch. It’s a real problem in my experience as I have sensitive RF circuitry.
