## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Issues:
- Pitfall : Inadequate decoupling causing signal integrity problems
- Solution : Use 0.1μF ceramic capacitors placed close to each power pin
- Implementation : Place decoupling capacitors within 5mm of device pins
Signal Integrity Problems:
- Pitfall : Improper termination leading to signal reflections
- Solution : Implement 100Ω differential termination at receiver end
- Implementation : Use precision resistors with 1% tolerance or better
Clock Distribution:
- Pitfall : Clock jitter affecting overall system performance
- Solution : Use high-quality clock sources with low jitter characteristics
- Implementation : Consider dedicated clock generator ICs for critical applications
### Compatibility Issues with Other Components
Deserializer Compatibility:
- Critical Requirement : Must pair with DS90CF387 deserializer
- Mismatch Issues : Different FPD Link versions are not backward compatible
- Solution : Verify device revision compatibility before design finalization
Microcontroller/GPU Interfaces:
- Timing Constraints : Ensure source device meets setup/hold time requirements
- Voltage
