摘要： A method and apparatus for improving printed circuit board signal layer transitions are described. In one embodiment, the method includes the formation of a first via within a printed circuit board (PCB). A second via is formed concurrently within the PCB. In one embodiment, the second via is positioned proximate the first via to enable electromagnetic coupling between the first and second vias. Following formation of the second via, the first and second vias are connected to provide a series connection between the first and second vias. In one embodiment, the series connection between the first and second vias reduces a stub length with respect to the first via to reduce and potentially eliminate stub resonance for, for example, short signal layer transitions. Other embodiments are described and claimed.

摘要： Component-less termination for electromagnetic couplers used in high speed/frequency differential signaling is described. In one embodiment, the apparatus includes a first signal line and a second signal line forming a differential pair, a first electromagnetic coupler to provide sampled electromagnetic signals from the first signal line, and a second electromagnetic coupler to provide sampled electromagnetic signals from the second signal line, wherein the first electromagnetic coupler is far end short circuited and wherein the second electromagnetic coupler is far end open circuited. Other embodiments are also described and claimed.

摘要： At least two sequences of predetermined reference times are established on respective ones of at least two communication lines. At least some of the reference times of at least one of the sequences occur out-of-phase with at least some of the reference times of another of the sequences. Digital data is encoded onto data signals on one or more communication lines such that a time difference between at least one of the data signals and the nearest one of the reference times on one of the communication lines is smaller than the time difference between the same data signal and the nearest one of the reference times on another one of the communication lines.
