## 2. Design Considerations
### 2.1 Common Design Pitfalls and Solutions
#### Pitfall 1: Improper Power Supply Decoupling
Problem : Insufficient decoupling causes frequency instability and increased phase noise
Solution :
- Implement three-stage decoupling: 10 µF bulk capacitor + 1 µF ceramic + 100 nF ceramic
- Place decoupling capacitors within 5 mm of EB23NUL power pins
- Use separate power planes for analog and digital sections
#### Pitfall 2: Thermal Management Issues
Problem : Self-heating affects frequency stability in high-density designs
Solution :
- Maintain minimum 2 mm clearance from heat-generating components
- Implement thermal vias under the component for heat dissipation
- Consider airflow direction in enclosure design
#### Pitfall 3: Signal Integrity Deg
