Clock and Timing Signal Board Layout Considerations
When laying out the system board, use the following guidelines:
Keep clock and timing signal paths as short as possible and route with 50
Ω impedance.
Use a serial termination resistor placed close to the clock buffer to minimize signal reflection. Use the following
equation to compute the resistor value:
Rterm = Rim – Rbuf
where Rim = trace characteristic impedance
Rbuf = clock buffer internal impedance.
