## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management :
- *Pitfall*: Inadequate heat dissipation in high-ambient temperature environments
- *Solution*: Implement active cooling or heat sinking; maintain junction temperature below 150°C
Power Supply Sequencing :
- *Pitfall*: Improper power-up sequencing causing latch-up conditions
- *Solution*: Follow manufacturer-recommended power sequencing; implement soft-start circuits
Signal Integrity :
- *Pitfall*: High-frequency signal degradation due to improper termination
- *Solution*: Use controlled impedance transmission lines with proper termination networks
### Compatibility Issues
Voltage Level Compatibility :
- Requires 3.3V core voltage with 5V tolerant I/O
- Incompatible with newer low-voltage (1.8V/2.5V) systems without level shifting
Clock Distribution :
- Maximum clock frequency of 200MHz
- Requires low-jitter clock sources for optimal performance
- May require external PLL components for specific timing requirements
Interface Standards :
- Native support for MIL-STD-1553 and SpaceWire protocols
- Limited compatibility with newer high-speed serial interfaces
### PCB Layout Recommendations
Power Distribution :
- Use separate power planes for analog and digital supplies
- Implement star-point grounding for noise-sensitive circuits
- Place decoupling capacitors within 5mm of power pins
Signal Routing :
- Maintain 50Ω characteristic impedance for critical signals
- Route differential pairs with consistent spacing and length matching
- Avoid crossing power plane splits with high-speed signals
Thermal Considerations :
- Provide adequate copper area for heat dissipation
- Use thermal vias under the package for improved heat transfer
- Consider thermal relief patterns for soldering processes
