# Switch between two TCXOs to feeding ADF4350

I need to design ADF4350 synthesizer that can use either one of two TCXOs.  Do you have any switch that can do this job?

The connection is as follows:

_______

TCXO2 ----->|______|

Thank you

• Hi Lotus,

I assume that the switch shares the supply voltage with the ADF4350(3.3V +/-10%) and the TCXO signals are single ended. If that is the case, you can use any of the following switches: ADG619/719/749/779.

For diferential TCXO signals the ADG636/736/787/772 can be used.

Regards,
