Abstract: An apparatus includes an integrated circuit package and a heatsink. The integrated circuit package includes a substrate, an integrated circuit, a first plurality of signal conductors, and a second plurality of signal conductors. The substrate includes a first surface and a second surface opposite the first surface. The integrated circuit is coupled to the first surface of the substrate. The first plurality of signal conductors are arranged along a periphery of the first surface of the substrate. The second plurality of signal conductors are arranged along a periphery of the second surface of the substrate. The heatsink includes a first portion positioned along the first surface of the substrate and a second portion positioned along the second surface of the substrate.

Abstract: Certain aspects of the present disclosure provide techniques for pinless interconnect for twinaxial cables to an IC. This includes a socket coupled to an integrated circuit (IC), a port structure coupled to the socket, and a ground connector inserted into the port structure. It further includes a twinaxial cable including a pair of conductors inserted through the ground connector to establish an electrical connection between the twinaxial cable and the IC.

Abstract: Channel predictive behavior and fault analysis may be provided. A forward time value may be determined comprising a time a forward signal takes to travel from a transmitter over a channel to the receiver. Next, a reflected time value may be determined comprising a time a reflected signal takes to travel to the receiver. The reflected signal may be associated with the forward signal. A discontinuity may then be determined to exist on the channel based on the forward time value and the reflected time value. The reflected signal may be caused by the discontinuity and a high impedance or low impedance at the transmitter present after the forward signal is sent.

Abstract: An apparatus includes a printed circuit board (PCB). The PCB includes a plurality of through-holes extending through the PCB between a PCB first surface and a PCB second surface that opposes the PCB first surface, where each through-hole includes a via extending from the PCB first surface to a depth within the through-hole that is distanced from the PCB second surface. An integrated circuit surface mount is connected at the PCB first surface with vias of the through-holes, and a cable interconnect assembly is surface mount connected at the PCB second surface. The cable interconnect assembly includes a plurality of contact pins, each contact pin extending within a corresponding through-hole and having a sufficient dimension to engage and electrically connect with the via of the corresponding through-hole so as to facilitate exchange of an electrical signal between the integrated circuit and the cable interconnect assembly.

Abstract: In one embodiment, a transmission system includes a transmitter, a receiver, and a filter operable at one of the transmitter and the receiver to remove channel impairments. The filter is operable according to a sum of a Gaussian function and a reciprocal of cosine function, wherein the Gaussian and reciprocal of cosine functions comprise tunable parameters to account for skew and channel asymmetry.
