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…
In high-speed PCB design, Deterministic Jitter (DJ) is the bounded, predictable timing error that directly limits signal integrity at multi-gigabit data rates. Unlike random jitter, DJ originates from identifiable sources like impedance mismatches, driver asymmetry, and power supply noise, making it a critical focus for reliable data transmission. Understanding its three dominant subtypes—Intersymbol Interference (ISI),…
