If the external clock supply is selected, the clock signal input ’CLK’ must fulfill certain requirements which are
described in the following:

1) Minimum Duty Cycle Factor: t
2) Maximum Duty Cycle Factor: t
Target Data Sheet
The high or low pulse width must not exceed the specified values, because the PLL needs a minimum pulse
width and must be spike filtered.
The duty cycle factor should be 0.5 but can deviate to the values limited by t
The PLL is triggered at the positive edge of the clock. If more than 2 edges are missing, a chip reset is
generated automatically.
