I have not used RC termination in a design, but have studied the laws
and equations which govern this type of termination.
I could not see any violations using RC termination for your
When utilizing RC termination, the following rules apply:
1. The value of the resistor is given by:
where Zo' is the loaded characteristic trace impedance.
2. The capacitor value is determined via:
C ~ 3Co
where Co represents total capacitance of the trace.
3. All stub lengths (including connection between capacitor and
resistor) should be kept as short as possible.
