FA1 noise test was shown here:

TAPR TICC noise test was shown here:

Tom ran my TICC data through Timelab to get pretty plots:
http://leapsecond.com/u/sims/gpsdo17/

however I think it is interesting to have the noise floor of the test set because it is a reference absolute value.

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

A frequency doubler and a frequency quintupler will be needed.

Options for the quintupler:

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
Wenzel's odd harmonic diode multiplier will also work:

Options for the doubler

The NIST JFET based frequency doubler
A BJT based variant of the above
A diode based frequency doubler (full wave rectifier plus output filter)

5 MHz -> 10 MHz is easy.

5 MHz -> 25 is harder. You can use a transistor biased to class B

with tuned circuits at the output, but to get an acceptable efficiency,

you'll have to adjust the collector current duty cycle, which is

f(input power, bias, etc) to keep Mr. Fourier happy.

You'll also need substantial filtering at the output.

Narrow filters are a natural enemy of phase stability.

You can find this & that useful here:
http://www.wenzel.com/documents/circuits1.htm

For 5->10 MHz, you can use something like the output amplifier

of my OCXO support board V2.0 and operate it in push-push doubler style.

See attachment. The amplifier/doubler is just the narrow strip below the
SMA

connector in the photo.

While I'm at it:

I've got the V2.0 boards just last week and tested it only with a Morion
MV89A

(on the back side) and the output amplifier in push pull without doubling.

With a 12V supply, it is easy to get +23 dBm out in nice quality. I have

also seen +26 dBm with some distortion. That could probably be healed

with adjusted bias, but for me +23 dBm is plenty. Enough to drive any

ring mixer or Timepod input even through a power splitter.

One could use a 1:4 splitter for 4 outputs with identical phase noise

and still have substantial signal power.

Watch your power meter or spectrum analyzer input. They might burn.

RF Transformers are $1.99 or so at Digikey. No DIY required.

There are 2 crystal or LC notches to reduce unwanted frequencies.

The Morion MV89 doubles internally from 5 to 10 MHz; on mine I can see

the 5 MHz fundamental on the scope. Every other 10 MHz sine is somewhat

higher or lower. Gives an unsteady scope picture. Uncaring. :-(

The board can lock the local VCXO to an incoming frequency or 1pps
reference,

produce a 1pps_out from the VCXO (3V3 CMOS level into 50 Ohms, good enough

for TTL) and indicate the signal level of the incoming ref frequency
(temp comp. diode

rectifier).

Supported oscillators are HP10811A, Morion, MTI-260, ECOC-2522-100.000-3FC

(affordable 100 MHz SC oven, avail. at DigiKey, abt. €100 ) and some el
cheapo others.

2FF-Phase detector and 1pps generation are in a $2 Xilinx Coolrunner II.
There are

strapping options for (5, 10, 100, x)MHz, Vtune sense etc. and optional
volt. regulators.

There are also lots of unused pins on a 100mil grid for experiments.

At $5 total for 10 boards + transport from PCBway it is cheap enough to
use it

just for mechanical mounting.

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.

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 3.333333x 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.

Hi all thank you I have now printed out the dater sheets for

The ICS570B NB3N502 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

Have to say that chip looks identical to what Burt sent earlier. Settings

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.

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.

For best timing work should I go for Sq wave or sine wave output and

Must do some work and reading so

Have to say that chip looks identical to what Burt sent earlier.

How
have you applied them. It seems really simple. Do you follow with

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 <djl@montana.com> wrote: > I looked for breakouts/eval boards for these.

Not sure if it's using the same device, may be ICS501... but this
appears to be the same functionality a bit cheaper:

I haven't tried one yet...
