- Pitfall : Signal degradation over long cable runs
- Solution : Implement proper termination and use high-quality shielded cables
### Compatibility Issues
Display Controller Compatibility :
- Requires TTL-compatible 24-bit RGB input
- Must match pixel clock frequency with display timing
- Verify voltage level compatibility (3.3V TTL)
Deserializer Pairing :
- Must use compatible DS90CF365/366 deserializers
- Ensure matching data rate capabilities
- Verify compatible control signal mapping
Power Supply Requirements :
- 3.3V core voltage with ±5% tolerance
- Separate analog and digital power domains
- Proper decoupling essential for performance
### PCB Layout Recommendations
Power Distribution :
```markdown
- Use separate power planes for analog and digital sections
- Implement star-point grounding for noise reduction
- Place decoupling capacitors (0.1μF) within 2mm of power pins
```
Signal Routing :
- Keep LVDS output pairs length-matched (±5mm)
- Maintain 100Ω differential impedance for LVDS pairs
- Route LVDS signals away from noisy digital circuits
- Use ground planes beneath LVDS transmission lines
Component Placement :
- Position close to display connector to minimize trace length
- Ensure adequate clearance for heat dissipation
- Group related components (crystals, decoupling caps) nearby
EMI Considerations :
- Implement proper shielding
