In some implementations, a substrate for coupling to an integrated circuit includes multiple layers. Each of the multiple layers has, in a particular region of the substrate, a repeating pattern of regions corresponding to power and ground. The multiple layers include (i) a top layer having, in the particular region, power contacts and ground contacts for coupling to an integrated circuit and (ii) a bottom layer having, in the particular region, power contacts and ground contacts for coupling to another device. At least one layer of the multiple layers has a repeating pattern of signal traces that extend along and are located between the regions corresponding to ground in the at least one layer.

Signal routing in integrated circuit packaging

An electrical connector may include a cord comprising wires and a plug extending from the cord. The plug may include a first top row of contacts included in a top portion of the plug and a first bottom row of contacts included in a bottom portion of the plug. The first top row of contacts may be coupled to the plurality of wires and include a first top differential signaling pair configured to carry signals according to a first communication protocol, and a second top differential signaling pair configured to carry signals according to a second communication protocol. The first bottom row of contacts may be coupled to the first top row of contacts and arranged to maintain a same arrangement of contacts and electrical paths the first top row of contacts to the plurality of wires when the plug is rotated one hundred and eighty degrees.

Electrical connector

An electrical receptacle may include a first row of electrical contacts extending along a side of the receptacle a first distance from an opening of the electrical receptacle and a second row of electrical contacts extending along the side of the receptacle a second distance from the opening of the electrical receptacle. The first row of electrical contacts may include a first receptacle differential signaling pair closer to a center of the first row of electrical contacts than a second receptacle differential signaling pair in the first row of electrical contacts. The second row of electrical contacts may include a third receptacle differential signaling pair closer to a center of the second row of electrical contacts than remaining contacts in the second row of electrical contacts.

Electrical receptacle with lower speed signaling contacts farther from center

An electrical connector may include a cord comprising a plurality of wires and a plug extending from the cord. The plug may include a top portion and an opposing bottom portion, which each include a plurality of contacts. The plurality of contacts on each of the top portion and opposing bottom portion may include at least two contacts with a first distance from a front portion of the plug and at least one contact with a second distance from the front of the plug. Each of the plurality of contacts on the top portion may be coupled to one of the plurality of wires and to one of the plurality of contacts on the bottom portion. The coupling may be configured to maintain a same arrangement of contacts and electrical paths to the plurality of wires when the plug is rotated one hundred eighty degrees.

Electrical connector and socket allowing connector to be rotated while preserving polarity

An electrical connector may include a cord comprising wires and a plug extending from the cord. The plug may include a first top row of contacts included in a top portion of the plug and a first bottom row of contacts included in a bottom portion of the plug. The first top row of contacts may be coupled to the plurality of wires and include a first top differential signaling pair configured to carry signals according to a first communication protocol, and a second top differential signaling pair configured to carry signals according to a second communication protocol. The first bottom row of contacts may be coupled to the first top row of contacts and arranged to maintain a same arrangement of contacts and electrical paths as the first top row of contacts to the plurality of wires when the plug is rotated one hundred and eighty degrees.
