| Popis: | 106 In the recent years, As the clock frequencies and data transmission rates in semiconductor systems steadily increase beyond the GHz range, the timing control of high-speed clocks and digital data, propagating signal traces on printed circuit boards(PCB), is becoming a critical issue in a high-speed digital circuit design. In high-speed data links, cables and connectors are required to transmit high speed signals between the various electronic devices or PCBs. This may cause SI(signal integrity)、electromagnetic interference (EMI) 、Electromagnetic Compatibility,(EMC) and power integrity, and other effects. Hence, during the design of state-of-the-art electronic systems, reducing the noise induced by trace is crucial. In the microstrip line structure, even a single transmission line with a certain distance also possible cause the accumulation of far-end crosstalk noise because the length of the transmission line is too long, and the far-end crosstalk noise affects the signal integrity. So this paper does simulation analysis for the far-end crosstalk suppression structure. This paper discusses the microstrip line structure using a serpentine structure to reduce the far-end crosstalk noise, by increasing the mutual capacitance so that the capacitive coupling ratio equal to the inductive coupling ratio to eliminate the far-end crosstalk noise, but the old serpentine structure suppression rate is not strong enough, so this paper proposes that the two new serpentine structures not only increase the suppression rate of the far-end crosstalk noise but also can make the impedance matching and the effective bandwidth is more wider. |
