## 2. Design Considerations
### Common Design Pitfalls and Solutions
Impedance Mismatch Issues
- *Problem*: Reflections due to improper differential impedance matching
- *Solution*: Maintain 100Ω differential impedance throughout transmission path
- *Implementation*: Use controlled impedance PCB stackup with 4-6 mil trace spacing
Power Supply Noise
- *Problem*: Switching noise coupling into analog sections
- *Solution*: Implement star power distribution with separate analog and digital grounds
- *Implementation*: Use ferrite beads and dedicated LDO regulators for clean analog supply
Signal Integrity Degradation
- *Problem*: Excessive jitter at higher data rates
- *Solution*: Minimize trace length differences between differential pairs
- *Implementation*: Keep length matching within 5 mil for optimal performance
ESD Protection
- *Problem*: Vulnerability to electrostatic discharge in exposed interfaces
- *Solution*: Incorporate TVS diodes on all external interface lines
- *Implementation*: Use bidirectional TVS arrays with low capacitance (<3pF)
