In my application I need a clock that is synchronized across several devices. (A detailed description of my system is given in an earlier question)

It appears achieving precision timing at a software level is not practical, therefore I am looking for a complete hardware solution. In this case I am looking for some sort of hardware that emits a clock that is completely synchronized across several nodes over the air.

Therefore, Are there low cost, short range (up to 20-30 meters) ICs that emit a clock synchronized across several wireless nodes? I cannot use GPS since my system will work mostly indoors.

  • \$\begingroup\$ @Harry Svensson It appears you guys didn't read the questions well. I am the author of both. This solution looks for a wireless synchronization mechanism. The earlier one looks for a system level solution. Their intent is same but the the real questions are completely different. \$\endgroup\$ – Ktc Jan 21 '18 at 4:59

  • \$\begingroup\$ @WesleyLee I would have agreed if I was asking a vs. b but I am not even sure it exists. You guys are real sticklers for rules which sometimes ruins the fun of this site. \$\endgroup\$ – Ktc Jan 21 '18 at 5:33
  • \$\begingroup\$ Hmm, I would suggest explicitly including the possibility of hardware based solutions on your original question, so people can recommend such IC if it exists. \$\endgroup\$ – Wesley Lee Jan 21 '18 at 5:38

    \$\begingroup\$ Nice find! You can answer your own question if this turns out to be a viable solution. \$\endgroup\$ – Wesley Lee Jan 21 '18 at 6:09
