Long Time, No See

I know. I was just starting to get some momentum posting to the blog on a semi-regular basis, and then — the drop off.

I am sorry about that. The Si5351A Breakout Board campaign consumed almost all of my work time. Given the limited amount of actual work time that I have, something had to give. So unfortunately it was blogging.

There’s also a bit more unfortunate news, as well as good news. The bad news is that I don’t foresee having the time to post as many posts as I would like, so for now, content will slow a bit. The good news is that is because I will be focusing my blogging efforts into the brand new Etherkit App Notes site at appnotes.etherkit.com. I’m going to be working hard to supply fun DIY projects that you can build using Etherkit products, starting with the Si5351A Breakout Board, and involving other Etherkit products as they come online.

In the meantime, it’s been very heartening to see all of the neat ways in which people have been incorporating the Si5351A Breakout Board into their own projects. For example, here’s a wonderful blog post and video from Mike N2HTT about how he constructed a multi-band VFO using the board and a 128×64 OLED display. I also received this link from Milan about how he use the board to clock his DVB-T dongle for SDR reception. It allowed him much greater frequency accuracy, as well as a way to slightly shift the ref osc frequency in order to see which signals are external and which are internally generated. All very neat stuff!

I won’t let this blog completely fade, but I will be putting most of my effort in to Etherkit-related work, so that’s where you’ll need to look to find most of my new content. Thanks for reading!

  1. Hi OM:
    I have si5353 board up and running, used the calibration example, but all see is Initializing the Si5351 you shoudn’t be seeing any of these in an endless loop. the examples seem to be OK!! ANY ideas?

  2. Hi Ross,

    From what you are describing, it sounds like the Si5351 isn’t initializing correctly or the I2C comms are not working correctly. However, the other examples seem to work ok for you? That is unusual. Perhaps you could try the old method of calibration, which is to simply output a 10.000000 MHz signal from the Si5351A with no correction factor, accurately measure the actual output frequency, then convert that manually to the correction factor in PPB that is necessary.
