PCB design for high-speed TTL
I am designing high-speed TTL-based processor.
I will be using fast AC, ACT and LVC series, so switching
frequencies will be in 100Mhz range with 1-3ns fronts.
I plan to use double-sided PCB, Bottom side will be VCC, top
side will be GND with high-speed traces on it.
Here are the questions:
1) What is optimal FR4 thickness for such high-speed schemes?
2) What is the optimal trace width for high-speed digital signals?
3) Do I need any termination for 5-10cm traces with 1-3ns fronts?
