Series termination resistor for IMI9531 Spread Spectrum Clock Generator

Question: What is the recommended  series termination resistor for the output 133 MHz clock lines from the IMI9531 Spread Spectrum Clock Generator?



The best termination depends on the trace length and trace impedance and capacitance being driven . A nominal value would be between 22 and 33 ohm. Make sure there are not any vias in the trace within the middle 3rd of the trace.
