$11.75
Clock generator in a box, with CLKIN for a reference clock and a Trinket for runtime configuration
There is a problem with the 3v power rail on the board. To work around it, either * apply the clock in signal only after power on * cut the 3v power trace, jumper to GPIO1, and use GPIO1 to “sequence” the power on
Based on Adafruit’s brekaout for the si5351: https://learn.adafruit.com/adafruit-si5351-clock-generator-breakout/overview
Resistors: 1k 0805 Caps: 2 x .47uF, 1x10uF 0805 SI5351 Trinket M0
