A PLL frequency synthesizer has an output frequency of 162.7 MHz. The reference is a 1-MHz crystal oscillator followed by a divider of 10. What is the main frequency divider ratio?
Added by Kara C.
Step 1
The reference frequency is given by a 1 MHz crystal oscillator divided by 10, which is: $f_{ref} = \frac{1 \text{ MHz}}{10} = 100 \text{ kHz}$ Show more…
