Need information regrading TCXO

Hello,

I am using Z7035 Evalution kit with ADRV9361. In that i want to use TCXO for PS clock(33.33Mhz) which is operated on 3.3 instead of 1.8V because i want higher stablibility. Is it possible to use 3.3V TCXO along with PS Bank 500.

Please guide me as soon as possible. 

Thanks

Re: Need information regrading TCXO

The Z7035 is an analog devices board, you might get help on the analog devices web site !

Two things you need to check ,
Look at the data sheet for the Zynq you have, and check those pins can work at 3v3 , and can you change the bank voltage. You will probably have to look at the schematic from analog devices for this ,

Look at the data sheet of the TCXO, see if that can run at 3v3, You will need to look at the BOM for the board from analog devices for this ,


And one final, a question,
why do you expect 3v3 to give you higher stability than 1v8 ?
