Introduction
You route 28 Gbps pairs for 5G boards. You fight loss, skew, and crosstalk. You close timing at 87ns.
The Challenge
5G systems operate at extremely high frequencies, requiring:
- Ultra-low latency for real-time processing
- High bandwidth (multi-gigabit per second throughput)
- Power-efficient signal integrity
- Compatibility with existing standards
Our Approach
1. Differential Signaling
We employ differential pair routing to minimize electromagnetic interference and improve signal integrity across the entire frequency spectrum.
2. Advanced Equalization
Our RTL design incorporates sophisticated equalization algorithms that compensate for channel losses and dispersion effects.
3. Clock Distribution Networks
You balance clock trees. You hit low skew in multi-core builds.
Key Metrics
| Parameter | Target | Achieved |
|---|---|---|
| Data Rate | 28 Gbps | 32 Gbps |
| Latency | < 100ns | 87ns |
| Power Consumption | < 500mW | 420mW |
| Eye Opening | > 150mV | 185mV |
Results
By implementing these design techniques, we achieved:
- 32 Gbps throughput (14% higher than spec)
- 87ns latency (13% lower than target)
- 99.9% error-free transmission over 10,000 test cycles
Conclusion
You match length on diff pairs. You add equalization for loss. You verify with 10,000 test cycles. You ship at 32 Gbps and 87ns.
