Switch between two TCXOs to feeding ADF4350

Dear Sir/Madam:

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:

                  _______

TCXO1 ----->|Switch |--------->ADF4350

TCXO2 ----->|______|

Thank you

    Hi Tim,

    In general, analog switches are not tested for jitter performance and the ADG852 is not an exception from this rule.

    I understand that performance is the key criteria in choosing the switch, but you have mentioned in your previous post that the ADG852's footprint is not common.I was just wondering if the pinout was contributing to the decision to remove the ADG852 from the parts considered for this application. Also, I would appreciate if you could explain what did you mean by "The footprint of ADG852 is not common."
