## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management
- *Pitfall*: Inadequate heat dissipation in high-temperature environments
- *Solution*: Implement proper thermal vias and heatsinking; maintain junction temperature below 150°C
Power Supply Sequencing
- *Pitfall*: Improper power-up sequencing causing latch-up conditions
- *Solution*: Implement controlled power sequencing with proper delay between core and I/O supplies
Signal Integrity
- *Pitfall*: Signal degradation in high-frequency applications
- *Solution*: Use impedance-matched transmission lines and proper termination
### Compatibility Issues
Voltage Level Compatibility
- Ensure interface compatibility with 3.3V and 5V systems
- Use level shifters when interfacing with lower voltage components (1.8V, 2.5V)
Clock Distribution
- Synchronization issues may arise when mixing with commercial-grade clock sources
- Recommended to use military-grade oscillators with tight stability specifications
EMI Considerations
- Susceptible to electromagnetic interference in unshielded environments
- Requires proper filtering and shielding implementation
### PCB Layout Recommendations
Power Distribution
- Use separate power planes for analog and digital supplies
- Implement star-point grounding for noise-sensitive analog circuits
- Place decoupling capacitors (100nF ceramic + 10μF tantalum) within 5mm of power pins
Signal Routing
- Maintain controlled impedance for high-speed signals (50Ω single-ended, 100Ω differential)
- Route critical signals on inner layers with adjacent ground planes
- Minimize via count in high-frequency signal paths
Thermal Management
- Use thermal relief patterns for power and ground connections
- Implement thermal vias under the package for heat dissipation
- Consider copper pour areas for additional heat spreading
