It works very well

SI5351 funktionier wie es sollHabe 5 Stüück bestellt und funktoinieren wie sie sollen.Stiftleiste hat eine Stift zu viel, ist aber keine Problem .

Perfect performance.

I purchased 3 of the DollaTek CJMCU-5351 Si5351A Clock Generators for a frequency synthesis project, and overall, it’s a capable tool with a few quirks worth noting. This module provides a wide range of output frequencies and has a stable PPL 25MHz crystal, making it versatile for radio projects, microcontroller timing, and other applications that need multiple clock outputs.One of the biggest strengths of this module is the Si5351A chip itself, which supports up to three independent clock outputs that can be configured with a fine degree of control through I2C. This flexibility allows for precise clock generation, which is great for custom electronics projects and frequency-based applications. The output frequencies are stable, and I didn’t observe any significant drift during continuous operation.However, there are a few limitations. For starters, the documentation that comes with it is minimal, so expect a bit of trial and error or the need to reference third-party guides, especially if you're new to clock generators.Lastly, while the I2C control is straightforward, it can be challenging to integrate with some microcontrollers due to voltage compatibility and pull-up resistors, which may require additional components.Overall, the DollaTek CJMCU-5351 works as advertised and is a good value for advanced users who need a configurable clock source. Just be prepared for some setup time and possibly a few adjustments to ensure reliable operation.
