A Noise-Free and Jitterless Cavity System to Distribute Clocks Over 10 GHz

摘要

We discuss a novel method using a cavity to deliver a high-frequency clock in ultra large-scale integration systems. This method can distribute global clock over 10 GHz without skew and electromagnetic interference noise. Since the cavity can be formed by a usual metallization or its extended process, it will be realized easier compared with other emerging technology such as photoelectric circuits. However, the cavity is thin and affected by energy dissipation on cavity walls. Considering energy dissipation, we discuss features of a cavity system
