- Pitfall : Improper power sequencing causing latch-up
- Solution : Follow manufacturer's recommended power-up sequence
Signal Integrity Challenges:
- Pitfall : Impedance mismatches causing signal reflections
- Solution : Maintain consistent 100Ω differential impedance throughout transmission path
- Pitfall : Excessive jitter due to poor clock quality
- Solution : Use low-jitter clock sources and proper termination
Thermal Management:
- Pitfall : Overheating in high-ambient temperature environments
- Solution : Ensure adequate airflow and consider thermal vias in PCB design
### Compatibility Issues with Other Components
