- Pitfall : Excessive trace length mismatches causing timing skew
- Solution : Maintain <5mm length matching between differential pairs
Power Supply Concerns:
- Pitfall : Inadequate decoupling causing power supply noise
- Solution : Implement 0.1μF and 10μF decoupling capacitors close to power pins
- Pitfall : Voltage spikes during hot-plug events
- Solution : Include TVS diodes on power and signal lines
### Compatibility Issues with Other Components
LVDS Receiver Compatibility:
- Compatible with : DS92LV011A, DS92LV012A, and other standard LVDS receivers
