It's like driving an Australian Roadtrain 500 meters down the street to the bakery to get a loaf of bread.
Jokes aside... These past days there are a lot of really nicely made informative videos on this channel here, keep it up !! Thanks !
Looking forward to seeing this come to life Steve. Very nice 👍
Nice Project. LCMXO3LF-6900C-S-EVN
might be worth looking at now as time has moved on. Mike's Electric Stuff introduced me to Lattice and the dev boards are a bargain but support ebbs off with time. If I remember correctly there are some X03 devices that aren't BGA so hand assembly is still feasible. Looking forward to the GPSDO with FPGA project.
@6:55 I think VHDL has 'rising_edge()' you can use there... [2c]
This MachXO2 dev board is really good and very affordable. I think Mike from mikeselectricstuff recommended it a couple of years ago as well.
super interesting thank you
Nice video, look forward to the rest. The whole FPGA thing is a bit over my head - would be handy to have a quick overview of the main constructs in the code (processes, architecture etc.).
Nice job👏👏👏👏👉
Thanks Steve. Is there a copy of the code somewhere as i found it hard to read from the video.
Great chanel, sub for you.Best regards.👍
Great video again. How do you ever find time for this with a full time job and a family?
@SDG, Are you going to place the PCB design and VHDL on your web site?
15:11 Do you have a link to his channel? I don't know him and it sounds like he creates some interesting content. Thanks

@@sdgelectronics Thanks!
@@pnjunction5689 Thanks!
Nice video and great idea running through a project like that with a useful piece of equipment. Not sure how far you want to go but you could even design the enclosure?
Yes, the enclosure is part of the project. There's some excellent online metal machine work suppliers which I've used before
Is this project open source ?
You could use SOC's for implementing your project, the linux system will get the time from NTP server and synchronize the clock with it.
as soon as I saw this.. i was like.. is this a tutorial for mjl? ^_^ nice to see the reference to it.. ^_^
I was thinking about sending him one! It was killing me seeing him trying to do precision timing on those clocks
SDG Electronics Yep, you should deffo send Martin one.......maybe add a sync pulse out if you haven't already.
Thank you. That was a great insight into your design. I was looking at doing the same sort of thing on a Mojo v2 using Verilog as a sort of FPGA self teaching project. I am probably going to use an LCD display but there is something "nice and retro" about a good old 7 segment though.
Just a suggestion, do a search for "time nuts ublox" before building this. There is a lot of info about the problems and feasibility. I've seen several projects where people have tried this, but it usually results in them buying a commercial unit. I'm no expert. I was planning to build something like this, and had someone else tell me the same thing I'm passing along here :-)

Thanks I'll have a look. So long as the 1pps output is good, it shouldn't be problematic
Just looking at buying one of these FPGA boards and what looks to be the same board (LCMXO2-7000HE-B-EVN ) doesn't have the crystal oscillator X2 on board, just the pads where one can be fitted. there are two schematics on the data sheet and one shows a 50MHz crystal oscillator while the other doesn't so is this just available on one specific board revision?
I'm not sure. The MachXO2 has an internal oscillator too so you can use it without the external oscillator
Good video, thanks. Might have been handy to add a link to the FPGA board you used. I can’t find it anywhere.
It should be there now. Thanks
Now if I could only find my magnifying glass so I could see the code
Do you have a link to the actual Lattice board used?
It's in the description now, thanks
Hi, i want ask about bst 863, do you still use it? Any problems with this stuff, can you make video about it after 6(?) months?
Hi, yes it gets used most days and still works perfectly. No issues with it at all.
fancy sending me the failed GPS to see if I can fix it ? (not likely but worth a shot!)
Does anyone else keep forgetting what fpga is every month and needs to spend time understanding. And then forget again and start All over again....
So the MachXO2 is a CPLD and not a FPGA (luckily ;-)
Technically, since it contains the FLASH etc and relatively low logic cell count
