Freescale Semiconductor
Note: Usually, the PLL's propagation delay from f
limit of the system. The upper frequency limit is found with the following formula: f = P / (t
in Hz, P is the lower of the dual modulus prescaler ratios, t
setup time in seconds. For example, with a 5 V supply, the f
time is 16 ns. Thus, if the 64/65 ratio is utilized, the upper frequency limit is f = P / (t
