Has anyone coded a PICDiv type of solution into a dsPIC33F chip using a 32-bit
Type B timer? I've been doing some experimentation over the past few days, and
I've had a few latency issues when using the internal clock, which is PLL
linked to the 10MHz external clock input. The problem shows

I have one of these and I really like the compact unit. I don't have any
equipment to compare it's accuracy other than my Nortel GPSDO and watching them
both on the scope. If you follow this thread there is a number of tips and
commands on the use of the RS232 output. There is also a
U.S. only, will ship in well packaged USPS Priority Mail box. $220.
E-mail me off-list if interested.
This is my back-up Trimble ThunderBolt with rev 3.0 firmware. It's been sitting
unused in a box for too long; it should be in some time-nut's lab listening to
birds.
Obviously used with tape
Hi
Both of these little beasts likely have much of the same basic smarts as their
older / bigger cousins. The OCXO may or may not be quite as super low
phase noise as some of the others. Based on that, I would expect them to
need to run for several days at least before you see what they really
I have been playing with one of those small, 2.75"by 4.5" GPSDOs that are
being sold on that auction site. Most of the ones I have seen any
discussion about have been Trimble, but this Symmetricom one looks similar
but is about half price. I have hooked it up a few times to see how fast it
can

Moin,
Looking at the phase data, you can see that jitter of the pulses
of two nodes is <+/-170ps, with the average being pretty much in a window
that is samler than +/-70ps.
For the other *DEV plots, I also added measruements of the Teensy 3.1

Moin,
We are building here some clock synchronization system and have done
some measurements. I am trying to do some sanity checks, but I am
not sure whether what I am interpreting into the data is actualy true.
Hence I would like to ask for
Hi
On an entirely different project, I happened to get diverted over to “ZVS
modules”.
They are the guts of an induction heater and are dirt cheap (as in less than
the price
of the OCXO). More or less, it’s the 3’ rack cabinet from 1935 done as solid
state for
$10 to $50.
If you had
