Change the VCXO in EVAL-HMC7044 board

A VCXO at 122.88MHz is mounted in EVAL-HMC7044 board, so the inputs to the PLL1 must be divisors of this frequency. My input has to be a signal at 10MHz so I would like to have another frequency in the VCXO, for example 100MHz.

Is it possible to connect an external VCXO through the CPOUT1 output and the OSCIN input? Or can I change the VCXO to another at 100MHz?


Thanks in advance.
