Quick PCB: TCXO Breakout

Dan Watson has published a new build:

There are some good, inexpensive TCXO modules on eBay that come in the slightly unusual package shown above. This breakout board allows you to mount one of the modules onto the small PCB and adapt it to standard 0.1″ breadboard-compatible headers. I have also included a few optional SMD components. There are spots for a power LED, a bypass capacitor on the supply rail, and a capacitor on the control voltage input.
Some of these modules don’t actually have a control voltage input on pin #1. Typically they have a small trimmer on top for adjusting the frequency, which is probably more useful for how these are commonly used. If you have access to a disciplined frequency reference such as a GPSDO, you should allow the module to warm up for 24 hours and then trim the frequency.

More details at The Sync Channel blog.  Project files available at Github.
