WebThe idea of optical clock distribution was first put forth in a seminal paper by J. W. Goodman et. al. in 1984 [6]. The primary motivation for optical clocking then was to minimize global clock skew. It was assumed that optical signals would be distributed at a high level on a chip or board with the lower levels of distribution done electrically. WebMay 30, 2024 · Stephen J. Mraz.
