Data Dependent Jitter and ISI in High Speed PCB Channel Loss and Reflections
In modern high-speed digital design, achieving reliable data transmission beyond 1 Gbps is no longer solely about logic levels and timing margins. The physical channel—the PCB traces, vias, connectors, and cables—becomes a lossy, frequency-dependent transmission line. Two of the most insidious signal integrity (SI) phenomena that degrade performance are Data Dependent Jitter and ISI in…
