#si5351a — Public Fediverse posts

I've recently used insights from this article to implement a sample rate step size 128 times smaller than previously supported in HackRF:

https://www.pa3fwm.nl/technotes/tn42a-si5351-programming.html

This means that sample rates around 20 Msps can be adjusted in steps of about 0.015 Hz. The precision is even better at lower sample rates.

I highly recommend reading it if you use #Si5351 in any projects. #Si5351A #Si5351B #Si5351C

@Bleijswijk

There's a data sheet for the #Si5351A and family here

https://www.skyworksinc.com/-/media/Skyworks/SL/documents/public/data-sheets/Si5351-B.pdf

Looks like there's a couple of related parts (A B C) in a few pinouts, and there's some additional application notes on the SkyWorks site with details of the I2C bus registers.

have fun!

@Bleijswijk neat! sounds like a fun project

That part looks very similar to this #Adafruit component

https://www.adafruit.com/product/2045

except for the blue vs red circuit board.

"The #Si5351A clock generator is an I2C controller clock generator. It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions."

Looks like they have a tutorial too.
