I want to design PLL circuit,and i confuse the selection of the reference frequency and channel space.I check some document,it is selected by 12.5kHz,25KHz and 50KHz and the channel space is selected the same frequency.Why not to select other frequency(<30MHz)?
And any other rule to define the reference frequency and channel space?
anybody can help me?
Thanks in advance.
