Adafruit Si5351A with Arduino Zero

I tried to connect the Si5351A with Arduino Zero from Protoneer but it does not work as described here:

https://learn.adafruit.com/adafruit-si5 ... g-and-test

I used exactly the proposed example library si5351. The Upload of the sketch was successful, but no output at the serial console at 9600 baud and also no signal was measureable at one of the three output channels of the clock generator.

Any proposals to solve this issue?

Thanks
Peter

check power and I2C lines...

There are Arduino libs that can be used to check for I2C devices and it might be that the address you are connecting to is not correct.
