Description

10MHz GPSDO V4.2 (1 of 4)

This is a high precision GPSDO ( GPS (GNSS) Disciplined Oscillator) with an output frequency of 10MHz.

The design is based on the publication in EEVBlog by Lars Walenius (RIP) but with several enhancements.

Much more information can be found on my Blog here : https://www.paulvdiyblogs.net/2023/06/gpsdo-version-4.html

You can also get the Arduino script from my Github site here : https://github.com/paulvee/Lars-GPSDO-V4.2

Keep in mind that many of the parts that I used are not critical, unless I specifically mentioned that in the Blog. If you find that a part is no longer available or not in stock, you can look for a replacement that has approximately the same specifications and use that. Just use common sense when looking for alternatives.
