Re: AD9559 : 0.1Hz loop bandwidth

Hi Paul,

Thank you for reply.

I've measured the system clock waveform, the voltage is 0.98Vpp square wave but the duty cycle is 46/54%.

Does this duty cycle affect the 0.1hz loop bandwidth ?

I read the TCXO vendor datasheet (Rakon, Vectron), and the duty cycle is normally 45/55%.

Could you let me know the recommended TCXO (or OCXO) part ?

Thanks and best regards.

MK
