摘要： Methods and apparatus for serial channel operation are disclosed. An N+1-level signaling scheme is used to transmit N staggered but overlapping NRZ sub-sequences concurrently on a serial channel. Each sequence has a bit rate R and an essential bandwidth of R Hz. The combined bit rate of the channel is N×R, but due to a lack of correlation between the sub-sequences, the essential bandwidth remains approximately R Hz. The signaling scheme also contains redundancy that allows some errors to be detected and/or corrected. Other embodiments are also described and claimed.

摘要： Circuit boards and methods for their manufacture are disclosed. The circuit boards carry high-speed signals using conductors formed to include lengthwise channels. The channels increase the surface area of the conductors, and therefore enhance the ability of the conductors to carry high-speed signals. In at least some embodiments, a discontinuity also exists between the dielectric constant within the channels and just outside the channels, which is believed to reduce signal loss into the dielectric material.

摘要： Methods of operating a packet network device having multiple serial channels crossing a backplane are disclosed. In at least one embodiment, a management function performs dynamic modifications to the packet network device configuration in response to detected backplane errors. These modifications can directly alter a characteristic of a channel that is generating errors, or can indirectly affect such a channel by directly altering a characteristic of an “aggressor” channel that is indicated as producing crosstalk on that channel. Other embodiments are also described and claimed.

摘要： A high-speed router backplane is disclosed. The router backplane uses differential signal pairs on multiple signal layers, each sandwiched between a pair of digital ground layers. To reduce routing complexity, at least some of the differential signal pairs route through a via pair, somewhere along their path, to a different signal layer. Specific via designs reduce differential signal distortion due to the via pair, allowing the backplane to operate reliably at differential signal rates in excess of 3 Gigabits per second. In particular, each via passes through nonfunctional conductive pads on selected digital ground plane layers, the pads separated from the remainder of its ground plane layer by a clearance, thereby modifying the impedance of the via and reducing reflections from the stubs created by the via.
