## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Design
- Pitfall : Inadequate decoupling causing voltage droops during peak processing
- Solution : Implement multi-stage decoupling with 100nF, 10μF, and 100μF capacitors
- Pitfall : Poor power sequencing leading to latch-up conditions
- Solution : Follow recommended power-up sequence: Core → I/O → Analog
Clock Distribution
- Pitfall : Clock jitter exceeding 50ps RMS affecting ADC performance
- Solution : Use low-jitter oscillators and dedicated clock distribution ICs
- Pitfall : Improper clock tree synthesis causing timing violations
- Solution : Implement balanced clock tree with matched trace lengths
Thermal Management
- Pitfall : Inadequate heatsinking causing thermal throttling
- Solution : Calculate thermal resistance (θJA < 15°C/W) and use appropriate cooling
- Pitfall : Poor airflow in enclosure design
- Solution : Implement forced air cooling for sustained high-performance operation
### Compatibility Issues with Other Components
Memory Interfaces
- DDR4 Compatibility : Requires careful impedance matching (40Ω ±10%)
- Flash Memory : Limited to SPI flash boot devices; verify timing compatibility
- External Peripherals : 3.3V LVCMOS I/O standards; level shifters needed for 1.8V devices
Analog Front-End Integration
- ADC Interface : Supports up to 4 simultaneous ADC channels at 16-bit resolution
- Clock Synchronization : Requires phase-locked loop (PLL) alignment with external clocks
- Signal Integrity : Sensitive to noise from switching power supplies
