When working with high-speed signaling, every interconnect matters. At gigabit rates, PCB traces behave as transmission lines, and improper termination can cause impedance mismatches, signal reflections, and serious performance degradation.
To ensure clean, reliable communication between devices, it’s critical to use the right line-termination techniques—especially when mixing I/O standards like LVPECL, LVDS, CML, HCSL, and LP-HCSL. The wrong approach can lead to I/O incompatibility, device malfunction, long-term reliability issues, or even hardware damage.
In this video, we break down the essentials of proper line termination for high-speed interfaces and explore how to maintain signal integrity across different technologies.
📘 What’s Covered in This Application Note:
• Transmission line basics and why termination matters
• DC coupling vs. AC coupling
• Driver output and receiver input voltage levels
• DC-coupling strategies for multiple driver types
• AC-coupling considerations for mixed-technology interfaces
• Best practices to prevent reflection, distortion, and device failure
