I have to ask: what frequency did your measuring instrument go up to? Did
you only have a strong 2nd harmonic? Or was everything above 2nd outside
the bandwidth of the measuring instrument?

[SI-LIST] clock 2nd harmonic
Sent by:
si-list-bounce@xxxxxxxxxxxxx
I am having an EMI problem with the second harmonic of a 65 MHz clock.
There is a strong emission at 130 MHz.
What is most likely causing the second harmonic and how can I reduce it?
The clock waveform does not look seriously distorted.
Thanks
