Si5351 PCB with Low Pass Filter

In today’s mail, the latest┬árevision to my Si5351 board arrived from For me, this board is really a prototype and proof of concept. It is a reusable building block. This module is streamlined I can import it into a larger design in KiCad, remove the headers, and go. The low pass filter is really designed for HF work. One could change the values and reformulate the lpf.

After the kids go to bed, I salvaged the parts from the last generation board and assembled one. It is always thrilling when it works right off the bat. This generation fixes a VCC problem, adds additional bypass capacitors, an extra [optional] header for using outputs two and three. Lastly, lots of markings (documentation on the board).
