CR-5000 High-Speed Design Methodology
- What is High-Speed Design?
- How industry drivers force high-speed and why is it (and signal integrity) important?
- What causes the problems?
- Harmonics, clock frequencies, sources of noise
- Noise Margins, definition, calculations, impact, considerations, timing, goals
Transmission lines as main problem cause:
- What is a transmission line?
- Transmission line effects on printed circuit boards
- Undershoot / Overshoot
- Ringback, Monotonicity, Reflection and Crosstalk
- Current paths on a PCB – return current
Timing and Board interconnect delay:
- What is Flight Time
- How to treat interconnect delay in timing
Printed circuit boards:

- Board Stack up
- Impedance control
- Transmission Line Impedance Zo, target impedance
- Drivers and receivers, switching characteristics
- When is it needed?
- What type of termination to choose
- Impact on the timing
- Control undershoot/overshoot by termination techniques
- When are topologies important?
- How do topologies affect signal integrity and timing?
- Coupling Types, causes and limits
- When crosstalk gets important, noise margins
- How can cross talk be minimized?
- Crosstalk and timing
Differential Signaling/Differential Pairs:
