AD9371 frequency stability

If the on board VCXO is changed, then the REF_CLK input to the chip should be an integer multiple of the VCXO.

Dear srimoyi,

Thanks for your reply, however, my question is actually related with which inputs are critical for the frequency stability, REF A or VCXO?

Both the REF_CLK input to the chip and the VCXO with good phase noise performance should be clean and jitter free for better performance.
