FINALLY, TAME THE SI5351!

The Si5351 is an incredibly helpful device, including several clock generators with numerous flexible programming choices that go well beyond its original function of offering a clock for digital circuitry. It has in specific discovered a area in RF projects, where it offers a inexpensive as well as efficient stand-in for a variable frequency oscillator in whatever from receivers to VNAs. It’s fair to state that programming the Si5351 isn’t the simplest of tasks though, as well as joining the different attempts to make this easier is [MR-DOS], who has produced an Si5351 library for the STM32 variety of ARM Cortex M processors. thankfully for those afflicted by the semiconductor shortage there’s the guidance that porting it to other architectures ought to only need the fairly workable task of modifying the i2c function for the new hardware.

Instead of being a full abstraction layer for frequency generation, this library offers functions to provide gain access to to the nuts-and-bolts of the chip such as PLL dividers. therefore there’s a requirement to comprehend the workings of a PLL as well as determine its parameters, while in return much much more versatility over the chip’s operation can be had. We such as this method even though it needs a bit much more work from the developer.

Over the years this gadget has drawn in a range of libraries, this isn’t the very first we’ve featured.
