## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Sequencing :
- Pitfall : Improper power-up sequence causing latch-up or permanent damage
- Solution : Implement sequenced power management using dedicated power controller ICs with controlled ramp rates
Clock Distribution :
- Pitfall : Clock jitter affecting ADC performance and communication timing
- Solution : Use low-jitter crystal oscillators with proper load capacitance matching and keep clock traces away from noisy digital signals
Thermal Management :
- Pitfall : Inadequate heat dissipation leading to thermal shutdown at high ambient temperatures
- Solution : Incorporate thermal vias in PCB design and consider active cooling for continuous high-load operation
### Compatibility Issues with Other Components
Memory Interfaces :
- Issue : Timing mismatches with external SDRAM operating above 133 MHz
- Resolution : Implement proper signal integrity measures including termination resistors and length-matched routing
Analog Front-End Components :
- Issue : Ground bounce affecting precision analog measurements
- Resolution : Use separate analog and digital ground planes with single-point connection near power supply
Communication Peripherals :
- Issue : Voltage level incompatibility with 5V legacy systems
- Resolution : Incorporate level shifters or use built-in fail-safe I/O features
