Wireless Distribution System Eliminates Dispersion In Clock Networks

摘要

As system operating frequency and projected die size increase, it has become more difficult to distribute clock signals across a chip. The resulting problems include larger R-C delays, tighter skew and jitter tolerance, and signal dispersion along metal interconnect paths. To reduce skew and the impact of dispersion, a compact, wireless clock distribution system with an external planar antenna has been proposed by Maxim's Ran Li, Silicon Laboratories' Xiaoling Guo, RF MicroDevices' Dong-Jun Yang, and Kenneth K. O from the University of Florida.
