LMX2595: Mismatch in critical noise model parameter and phase noise graphs

Part Number: LMX2595

Great discussion Ferron and Dean - a pleasure to read.

My question is one Farron already asked but I did not find the answer from Dean: What is the exact part number of the Wenzel oscillator that TI used to make its measurements?

Wenzel makes a series of OCXO's from very good (Sprinter) to even better (Sprinter Premium) to out of this world (Premium Ultra-Low Noise - the model Ferron is using) - but with each step the price also jumps substantially.

I need to make a 15 GHz LO with the LMX2595 and will be perfectly happy with the noise shown in Figure 3 of the data sheet. I am hoping that I can stay in the Sprinter series (at 200 MHz) rather than go to the ULN series, so it would be very nice to know the exact model TI used for these measurements.

Thank you,

Tony

  • Tony,

    It might be overkill, but what we use is the Wenzel 501-4623G.  It's +13 dBm, so we put a 10 dB limiter after it before OSCin.

    For the OSCin reference, take the phase noise of this and multiply up by 20*log(Fout/Fosc) and then subtract this from your measurement.  But for this reference, it's far enough below the PLL noise that it's not necessary to subtract it off.

    Or what I would do is enter your phase noise in PLLatinum Sim and see if it is impacting the close in PLL noise.

    Regards,
    Dean
