Abstract: Methods and apparatus to facilitate routing of high-speed data channels are described herein. Under one aspect, a high-speed data channel is routed between an integrated circuit (IC) and a high-speed data connector mounted to a multilayer printed circuit board as part of a circuit assembly. The circuit assembly includes a signal pathway providing a high-speed data channel from the integrated circuit to the high-speed data connector, wherein a portion of the signal pathway includes an axial cable, such as a twin axial cable. The high-speed data channel may comprise a multi-lane data channel and may be bi-directional.

Abstract: Methods and apparatus for utilizing flexible (flex) circuit technology and/or axial cable to facilitate routing of high-speed data channels are described herein. Under one aspect, a high-speed data channel if routed between an integrated circuit (IC) and a high-speed data connector mounted to a multilayer printed circuit board as part of a circuit assembly. The circuit assembly includes a signal pathway providing a high-speed data channel from the integrated circuit to the high-speed data connector, wherein a portion of the signal pathway includes a flex circuit or axial cable.

Abstract: The present disclosure provides techniques for decreasing vertical crosstalk in a stripline. An apparatus may include a conductor bracketed by ground layers. The conductor may have a horizontal crosstalk. A vertical component may be coupled to the conductor. The vertical component may have a vertical crosstalk cancelled by the horizontal crosstalk.
