## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Improper Termination
- Issue : Missing or incorrect termination resistors causing signal reflections
- Solution : Place 100Ω differential termination resistor close to receiver inputs, maintain controlled impedance (100Ω differential)
Pitfall 2: Power Supply Noise
- Issue : Switching noise from DC-DC converters coupling into analog sections
- Solution : Implement proper power supply decoupling with 0.1μF and 10μF capacitors placed within 5mm of power pins, use separate analog and digital ground planes
Pitfall 3: Signal Integrity Degradation
- Issue : Excessive jitter and bit errors due to poor PCB layout
- Solution : Maintain differential pair routing with consistent spacing, avoid vias in critical signal paths, use ground planes as reference
Pitfall 4: ESD Vulnerability
- Issue : LVDS pins susceptible to electrostatic discharge damage
- Solution : Incorporate TVS diodes on LVDS lines, follow proper ESD handling procedures during assembly
### Compatibility Issues
Power Supply Compatibility :
- Requires clean 3.3V supply with <50mV ripple
- Incompatible with 5V systems without level shifting
- Sensitive to power sequencing with other system components
