Hi :
Thank you for the reply.
I checked the UG-161.pdf. Look like the evaluation board doesn't have
connector for the exteranl VCO, which is a basic requirement for our
application. So far I only found the UG-536.pdf has such possibility. We
wish the phase noise is as low as possible. An internal TCXO is quite
welcome but we can use external clock. At the beginning of the test, we
just start the frequency between 100Mhz to 150Mhz. But in the further
experiment, we need something can scan between 500Mhz to 1500Mhz. If you
can suggest any evaluation board similar to UG-536-- can be used with
external VCO as well as integrated with TCXO. That would be perfect!
