138 / 251 page  Electrical characteristics STM32H757xI 138/251 DS12931 Rev 1 6.3.9 External clock source characteristics High-speed external user clock generated from an external source In bypass mode the HSE oscillator is switched off and the input pin is a standard I/O. The external clock signal has to respect the Table 72: I/O static characteristics. However, the recommended clock input waveform is shown in Figure 21. Figure 21.
