Re: [time-nuts] 5 Mhz to 10 Mhz and 25 Mhz
Hi Bob thank you The reason for the original question was because I am using a leobodner reference but I require 27 mhz for the LNB 25 mhz for the phase lock loop at Ghz and 10 Mhz for the IF receiver so the leobod unit although being exceedingly good it only has 2 outputs so I thought of 5 to 10 and 5 to 25 add ones might be the answer my spectrum analyser uses a 100 mhz reference so I realise your opening line Please can we talk of line as I do want to learn about phase noise Paul -Original Message- From: time-nuts [mailto:time-nuts-boun...@lists.febo.com] On Behalf Of Bob kb8tq Sent: 12 September 2019 23:19 To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] 5 Mhz to 10 Mhz and 25 Mhz Hi If that's the objective then the correct answer is: "none of the above" :) For a low noise microwave chain, you want to go as high as you can with a crystal oscillator in the first step. That gets you into the 100 to 200 MHz range as the first step up from your low frequency standard. There are a lot of reasons why. Bottom line is that it's how you get the best noise out of the chain. Depending on the offset involved, and what you are comparing to, it may be better by as much as 20 to 40 db.

Re: [time-nuts] 5 Mhz to 10 Mhz and 25 Mhz
Hi Paul. PLL's of course can introduce phase-noise, as well as remove it. Certainly if the reference 5 MHz is (phase)noisy then a PLL can clean that up, but if you multiply it (before cleaning) it gets much worse. The multipliers themselves as someone else may chime in, can add to that I suspect too. I missed your original question, so did not realise you wanted to multiply up that far. Do you subscribe to Dubus? There's a description of a 122 GHz system in the current issue, using (from what I can gather) IC's used for collision avoidance/adaptive-cruise control etc, in modern vehicles.. PL locked (sort-of) to a GPS PPS source too, phase noisy at 122 GHz, but good enough for FM voice it seems! http://www.marsport.org.uk/dubus/last.htm (Just the front cover.) There is a sample full issue at https://www.dropbox.com/s/6gusksmazh7wmyy/DUBUS412w.pdf?dl=0 (that describes a 134 GHz transverter) If you've not come across that publication before. 73 Paul.

Re: [time-nuts] 5 Mhz to 10 Mhz and 25 Mhz
Don, don't worry too much about soldering the 8-pin SOIC's. You've been soldering 0.05" pitch TO-92's for decades. And each 4-pin side of a SOIC is 0.05" pitch as well. Rather than use an adapter with perfboard, I'd advise going with dead-bug with all grounded SOIC pins going straight to copper PCB and the other ones flying. The flying SOIC pins you can stagger-bend to make them easier to tack parts to. Tim N3QE On Tue, Sep 10, 2019 at 8:32 AM djl wrote: > I looked for breakouts/eval boards for these.

Re: [time-nuts] 5 Mhz to 10 Mhz and 25 Mhz
I looked at all of the details and a breakout board works. These are SOIC-8's so the pin spacing is 1/2 of a normal IC. Believe .05". But still solderable. The NB3N502 is just a bit cheaper then the others and at least a bit of application data is out there. Another approach would be dead bug style on a copper ground plain. It will work.

Hi all thank you I have now printed out the dater sheets for The ICS570BNB3N502 ICS 512 These are all new to me so my next question are there any PCB's available for any of the above For best timing work should I go for Sq wave or sine wave output and out of the 3 is their a preference Must do some work and reading so Thank you to all Paul B south coast UK -Original Message- From: time-nuts [mailto:time-nuts-boun...@lists.febo.com] On Behalf Of paul swed Sent: 09 September 2019 20:10 To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] 5 Mhz to 10 Mhz and 25 Mhz Have to say that chip looks identical to what Burt sent earlier.

You might look at the NB3N502 PLL mult chip. I've used this chip on my rubidium interface board and other projects. It's cheap, current production and does a number of multipliers from 2X 2.5X 3X 3.33x 4X and 5X Available from Mouser and others. I'm using one in a hybrid CW transmitter as a nearly coil-less scheme with a 6CL6 final. all 5 bands from either a 80 meter or 40 meter crystal. Keys really clean too.

Re: [time-nuts] 5 Mhz to 10 Mhz and 25 Mhz
Hi A lot depends on what your end use is and what you have to work with. There are Altera FPGA boards that have built in PLL’s that will accept a 5 MHz input. You can generate just about anything with them. 10 and 25 MHz (plus 1 pps) with multiple outputs of each would be pretty easy. Phase noise / jitter might not be super duper, but how good is your source? What are you driving? It may well be good enough.

Re: [time-nuts] 5 Mhz to 10 Mhz and 25 Mhz
A frequency doubler and a frequency quintupler will be needed. Options for the quintupler: 1) Convert to square wave and isolate the desired 25MHz output using filters. A bandpass filter is a poor choice if high phase stability is required. A high pass filter supplemented with series tuned shunt traps for the unwanted harmonics can provide higher phase stability 2) Wenzel's odd harmonic diode multiplier will also work: http://techlib.com/files/RFDesign2.pdf Options for the doubler 1) The NIST JFET based frequency doubler 2) A BJT based variant of the above 3) A diode based frequency doubler (full wave rectifier plus output filter) Bruce > On 09 September 2019 at 00:02 Paul Bicknell wrote: > > > Dear all > > Can any one point me in the direction of a circuit that can convert > 5 Mhz signal to give me 2 outputs one at 10 Mhz and another at 25 Mhz > > > Regards Paul B > > > ___ > time-nuts mailing list -- time-nuts@lists.febo.com > To unsubscribe, go to > http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com > and follow the instructions there. ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
