A good list of checks to make before committing the design of a new printed circuit board:
- EMI & Signal Integrity checks:
Good PCB Design Checklist
PCB Track Impedance
Clocked busses often need impedance controlled tracking to avoid the posibility of false clock signals caused by an impedance mismatch. As semiconductor devices have become faster and faster they have become much more susceptible to issues caused by signal noise. The problem relates to any type of clocked interface where a device you will transfer data to or from automatically moves on to the next data bit, byte or word every time it see’s a new clock edge.
