## 2. Design Considerations
### Common Design Pitfalls and Solutions
| Pitfall | Solution |
|---------|----------|
| Voltage droop during transient loads | Use low-ESR ceramic capacitors (10–100 µF) near power pins. |
| Signal integrity issues | Implement impedance-matched traces for high-speed I/Os. |
| Thermal runaway | Integrate temperature sensors and throttling protocols. |
### Compatibility Issues
- Voltage mismatches : Incompatible with 5V TTL logic without level shifters.
- Clock synchronization : Requires PLL alignment with host processors (e.g., AMD EPYC™).
- Firmware dependencies : Needs UEFI/BIOS support for power-state transitions.
### PCB Layout Recommendations
- Power planes : Use dedicated layers for VDD and GND to minimize noise.
- Decoupling : Place 0.1 µF and 10 µF capacitors within 5 mm of supply pins.
- Thermal vias : Add under the exposed pad for heat dissipation to inner layers.
- High-speed signals : Route differential pairs with length matching (±0.1 mm tolerance).
