1. This value could be an oscillator input or a series resonant frequency from a crystal. If used as an oscillator
2. Use the component values recommended by the crystal manufacturer.
3. This parameter applies when driving the clock input with an oscillator.
4. The reference-clock input slope should not exceed more than 2.5 V/nS to ensure proper PLL operation
