  • Publication number: 20080075070
    Abstract: A circuit board comprises signaling through-holes that pass through a plurality of layers, including signal trace and digital ground plane layers, and power reference plane layers. Clearances are set to achieve a desired impedance characteristic for the through-holes. At a power reference plane layer, the clearance is defined around multiple neighboring through-holes.

  • Publication number: 20080066951
    Abstract: A circuit board comprises a center segment distributing power and low-speed signaling, and outer segments for high-speed signaling. The segments use dielectric materials with different dielectric constants, with the outer segments supporting higher-speed signal transmission.

  • Publication number: 20070039171
    Abstract: Method and apparatus are disclosed for flow control over Point-to-Point Protocol (PPP) data links. A method of negotiating such flow control between two PPP peers is disclosed, along with methods for operating flow control across a PPP link. In one embodiment, flow control frames carry an IEEE802.3x MAC control frame payload—the PPP implementation repackages such frames as MAC control frames and passes them to a MAC, which performs flow control. In another embodiment, flow control frames allow flow control commands to be applied differently to different service classes such that PPP flow can be controlled on a per-class basis.

  • Publication number: 20050023241
    Abstract: The disclosed board fabrication techniques and design features enable the construction of a reliable, high-layer-count, and economical backplane for routers and the like that require a large number of signaling paths across the backplane at speeds of 2.5 Gbps or greater, as well as distribution of significant amounts of power to router components. The disclosed techniques and features allow relatively thick (e.g., three- or four-ounce copper) power distribution planes to be combined with large numbers of high-speed signaling layers in a common backplane. Using traditional techniques, such a construction would not be possible because of the number of layers required and the thickness of the power distribution layers. The disclosed embodiments use novel layer arrangements, material selection, processing techniques, and panel features to produce the desired high-speed layers and low-noise high-power distribution layers in a single mechanically stable board.
