I'm not an expert on this matter so I will give you the information
I have.
TCXO version has a SMD TAITIEN TT Crystal Oscillator with these
Phase Noise parameters:
- 100Hz : typ. -130 dBc/Hz,
- 1kHz : typ. -145 dBc/Hz,
- 10kHz : typ. -154 dBc/Hz.
OCXO version has a PTH TAITIEN NI Crystal Oscillator with these
Phase Noise parameters:
- 1Hz : typ. -95 dBc/Hz,
- 10Hz : typ. -125 dBc/Hz,
- 100Hz : typ. -140 dBc/Hz,
- 1kHz : typ. -148 dBc/Hz,
- 10kHz : typ. -152 dBc/Hz.
A fact to know is that for the choice of the S3 oscillator the
important was to have in that order, a good accuracy, a good
precision and then correct reception performances.
The internal 10MHz goes out of the S3 with a minimal conditioning
circuit so its characteristics are not impacted. It is different
regarding the receiver performance because there is an Si5338 which
generates the internal needed clocks.

Sorry I should have changed the title.
Hello Vianney, I have asked Elad twice
about the PN performance of the TCXO and OCXO of the FDM- S3
without a response. Can you please help with this?
Many thanks
Conrad Farlow
