An apparatus comprises a crosstalk cancelation circuit comprising a plurality of taps to output signals based on a signal transmitted via a first data line; and a summation circuit to combine a signal received by a second data line with the signals output by the plurality of taps to reduce near-end crosstalk present in the signal received by the second data line.

Near-end crosstalk cancellation system

An apparatus, such as a re-driver, can include a receiver port coupled to a first link partner across a first link; a transmitter port coupled to a second link partner across a second link; and a power management (PM) controller implemented in hardware. The PM controller can detect a PM control signal, determine a PM state for the apparatus based on the PM control signal, and cause the apparatus to enter the PM state. The apparatus can transmit electrical signals to the second link partner based on the PM state. The PM management control signal can include a clock request, an electrical idle, a common mode voltage, or other electrical signal indicative of a PM link state change of a link partner coupled to the re-driver.

Power management of re-driver devices

In some embodiments, a micro-via structure design for high performance integrated circuits is presented. In this regard, an integrated circuit chip package is introduced having a dielectric layer, a plated throughhole in the dielectric layer, and a micro-via coupled with the plated throughhole, wherein the micro-via forms a path around an axis. Other embodiments are also disclosed and claimed.

Micro-via structure design for high performance integrated circuits

According to embodiments, small holes or openings may be cut on or through the ground plane(s) adjacent to a selected trace line, so that C and L will be changed accordingly. Then phase velocity will also be changed. As a result, the flying time from one location or point to a different location or point of the transmission line will also be changed. This concept applies to a single trace. Similarly, this concept may be applied to one trace of a differential pair of traces (e.g., so that the two parts of the differential signal transmitted at one point in time at a location on the pair arrive at the same time at another location of the pair).

Skew compensation by changing ground parasitic for traces

A multi-band antenna comprises a first conductive layer having one or more parasitic patches, a second conductive layer having a plurality of radiating patches, and a third conductive layer having a ground patch. The first, second and third conductive layers may be separated by first and second substrate layers. The second conductive layer may comprise a first radiating patch having dimensions selected to radiate signals within a first frequency spectrum and second radiating patches having dimensions selected to radiate signals within a second frequency spectrum. In wireless local area network (WLAN) embodiments, the first frequency spectrum may comprise a frequency band ranging from approximately 5.1 to 5.9 GHz, and the second frequency spectrum may comprise frequency bands ranging from approximately 2.4 to 2.5 GHz.
