HMC783LP6C Crystal Oscilator

Hello,

 

The demo-board of HMC783 uses a VCXO. However, when measuring it on a spectrum analyser I can verify that the frequency actually drifts some few kHz per second, with LOCK aquired by the PLL.

 

 

I am wondering if using a TCXO would supress this, or if this continuous frequency shift has to do with the PLL itself.

 

P.S: The VCXO the demo-board has is CVHD-950-180353.

 

Kind Regards,
Hugo Santos
