- Cost Considerations : Higher per-unit cost compared to discrete solutions
- Power Sequencing : Requires careful power-up/down sequencing in mixed-voltage systems
- Thermal Management : May require thermal vias in high-density layouts
## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Improper Power Supply Decoupling
- Issue : Insufficient decoupling causing signal integrity problems
- Solution : Use 100nF ceramic capacitor within 2mm of each power pin, plus 10μF bulk capacitor per power domain
Pitfall 2: Incorrect Termination
- Issue : Signal reflections due to improper transmission line termination
- Solution : Implement series termination resistors (22-50Ω) close to driver outputs
Pitfall 3: Ground Bounce
- Issue : Simultaneous switching noise affecting signal quality
- Solution : Use multiple ground connections and optimize return paths
Pitfall 4: Thermal Management
- Issue : Overheating in high-frequency applications
- Solution : Implement thermal vias and adequate copper pour for heat dissipation
### Compatibility Issues with Other Components
