please try to join our upcoming meeting about opening the FPGA code of the time card https://www.linkedin.com/feed/update/urn:li:activity:6909908...

Production version will come today or tomorrow. Check the github

I sent send you a prototype if you are willing to help with some bug hunting

Thats exactly the point for this project. Also, I am hoping once we release the FPGA HDL files, the community will start adding more features like IRIG-B output, etc...

Yes, with the difference on how to present the time to the system, just a PHC

That is not true. First of all, the reason why we used the Alinx module (which you can buy of ebay as well as Amazon), was to make it easier for the community to manufacture and bu…

Just give us a bit of time. We had to use some IPs that due to licensing limitations prohibited us to release the source and we were only allowed to release the bin files. We are r…

You are right. This sentence was not supposed to be a literal description of what is the best way to build the card. It was more referring to the fact the building this card is not…

I have been working on a version with two GNSS receivers L1/L2 and L1/L5. The SA53 receives two PPS inputs and that allows you to detect Spoofing and Jamming. Again, I like to emph…

Of course we go inspired by the Google Spanner project and what they have published over a decade ago. Hats off to the Google Spanner team

Of course we are not going to build the card in the lab with assembling SMD parts. This was more a way to explain that building such a card should not be out of access for anyone

Most (if not all) our switches in the datacenter are capable to perform as transparent clocks. With transparent clocks you can keep the time sync error down to less than 5ns per ho…

Again, invented might be too strong. This is an abstraction of what you need minimally to build a time server on an open source basis. We appreciate and are humble to other product…

Please excuse the language “invented”. We simply meant “came up with a form factor” of having the MAC+GNSS present via PCIe bus as a POSIX clock similar to a NIC with hardware time…

I am very thankful to all of you putting all these questions and answers. We have a bi-weekly meeting under the open compute project and you can find previous talks there too. www.…

That’s a good question. GNSS gives you a 1 pulse per second signal. It is often with 20ns of accuracy. Now you need to interpolate nanoseconds between consecutive 1pps pulses. This…
