cdcd72010 frequency requirement 1

duuk lee

Hello,

If I design a circuit using CDCD72010 without using the same frequency selection of its EVB, then what will be the frequency relationship requirement for inputs: VCXO and PRI-REF, in order to get a particular output frequency ( for example, 228 MHz or 200 MHz, respectively ) ?

Thank you,

For PLL lock: Reference / M Divider = VCXO Frequency / N Divider
For output frequency: Output Freq = VCXO Frequency / Output Divider.
