LMX2594: Recommended 100MHz Clock Phase Noise?

Go Bravos

Part Number: LMX2594

In using the LMX2594 and tuning to the highest frequency, what would you recommend the 100MHz clock phase noise to be to achieve the phase noise plots in the datasheet?

Thank you.

Whatever you use, the phase noise will be multiplied up by 20*log(Fout/100 MHz).

For the close-in phase noise at 100 MHz, a 100 MHz Wenzel oscillator is what we use.

At farther offsets, like >1 kHz, then we have used oscillators, such as the Vectron VC-708 XO and there are also other choices.
