High-Speed Link Validation in PAM4 Interfaces: How to test intra-pair skew and its BER impact

Exclusive Technical White Paper

As next-generation standards push frequencies higher, minor physical or electrical length mismatches within a differential pair introduce timing skew. This structural imbalance fundamentally limits performance in multi-level PAM4 architectures.

What you will learn inside:

  • Intra-Pair Skew Mechanisms: Understand the real-world impact of fiber-weave effects and routing asymmetry on high-frequency channels.
  • BER Degradation: Analyze direct empirical measurement data linking phase mismatch to eye-closure and bit errors.
  • Advanced Emulation Layouts: Discover testing configurations using a Dual-Transmitter BERT architecture to accurately identify skew thresholds.
