3) Not subject to production test - verified by design/characterization
Final Data Sheet
The high or low pulse width must not exceed the specified values, because the PLL needs a minimum pulse
The PLL is triggered at the positive edge of the clock; if more than 2 edges are missing, a chip reset is
width and must be spike filtered.
The duty cycle factor should be 0.5 but can deviate to the values limited by t
generated automatically.
