STM32H743 - What are the limits for external clock sources?

The STM32H743 supports external clock sources (HSE bypass). What are the requirements for the clock signal (besides 50% duty cycle)? output voltage? min and max frequency supported?

Thanks

Check the datasheet 6.3.8 External clock source characteristics: 4 .. 50 MHz
