1MHz output impedance query?
Hi,
I am breadboarding my latest GPSDO using a ublox NEO-7 GPS receiver. I have a very stable phase lock using a 100MHz output from the receiver and a divided 10MHz OCXO clock.
I have used the attached circuit to ptovide a 50Ω output, and I'm experimenting with the square-to-sine converter also shown. What I don't know how to calculate is the output impedance which I would like to be 50Ω.
Would anyone help please?
