Bullseye LNB TCXO Output Details

Hi,

I’m looking for some more detailed information on the 25 MHz TCXO output of the Bullseye LNB.

Can such information be made available? A minimal, redacted schematic of just the TCXO section please? What is the output impedance? What is Vpp?

I am using the Bullseye LNB in an application where I’m also observing the actual TCXO frequency - for fine frequency correction in DSP of the actual received signal.

Many thanks,
Christian

Not a direct answer, but the realigment procedure is being made available here: Bullseye-Calibrator/Bullseye LO Re-Alignment Procedure.pdf at main · g4eml/Bullseye-Calibrator · GitHub

There’s also an adaptation circuit included for the ‘red port’, which may help answer your questions.
