Set Up PLL for RM48L952



Hello,

I am trying to understand the technical reference manual on how to configure the PLL. In the example given the following values were calculated:

NR = 5

NS = 20

NF = 72

NV =0.036

OD = 2

R = 1

When it is time to choose NF's value, it chooses it to be 72, which doesn't make sense since Output CLK = (Fin/NR)*NF, which would make it necessary that NR = 4, or NF = 90. Is it a typo? I really did not understand why it chose NF = 72
