Length : 3 days
This course is part 1 of a training series on “Understanding High Frequency PCB Design - High-Speed, RF, and EMI
Part 1: Essential High-speed PCB Design for Signal Integrity (3 days)
Part 1 applies basic physical principles to develop an understanding of the key issues of high-speed design, from controlling reflections and crosstalk to the design of the power distribution system and the PCB layer structure.
“What if” simulation examples show the effects of varying different parameters, with practical issues considered throughout.
The techniques developed can be applied immediately to improve PCB design, without EDA SI tools, but the course also provides a secure foundation for understanding how to benefit from SI tools.
To complete the Part 1, you could attend the Part 2: PCB Design at RF - multi Gigabit Transmission, EMI Control, and PCB Materials (2 days)
- High-speed design overview. What is high-speed? Signal integrity issues for design and layout.

- Track impedance, reflections and terminations. Practical PCB limits. Input impedance, signal propagation and reflection. Impedance control and termination strategies.
- Differential transmission. Differential and common mode currents, routing and termination.
- Crosstalk. Near end and far end crosstalk, effects of coupled length, track geometry, multiple tracks.
- ICs for high-speed design. I/O characteristics, I/V curves, transition timing. Behavioral device models, IBIS standards.
- PCB routing topologies. Constraints. Discontinuities: connectors, vias, stubs, branching. Equalization, loading, clock distribution.
