Abstract: A shielded SODIMM system for reducing RF emissions of a SODIMM connector is disclosed herein. SODIMM connector RFI presently interferes with connectivity and is also an obstacle for higher speed memory applications. The shielded SODIMM system includes a SODIMM connector that is at least partially housed by a SODIMM connector shield, to partially and/or substantially reduce or block RF emissions from the SODIMM connector. The SODIMM connector shield is at least partially conductive and is coupled to landing pads on a surface of a motherboard printed circuit board (“PCB”). The landing pads of the motherboard PCB that are coupled to the SODIMM connector shield are coupled to ground, which grounds the SODIMM connector shield. Grounding the SODIMM connector shield that at least partially houses the SODIMM connector reduces RF emissions from the SODIMM connector during information transfer operations.

Abstract: Generally, this disclosure provides systems and devices for reduction of crosstalk between routed signals. A system may include a first pair of signal lines and a second pair of signal lines and each of the pairs of signal lines include a positive signal line and a negative signal line to transmit a differential signal. The system may also include an alternating current coupling capacitor (AC cap) associated with each of the positive signal lines and each of the negative signal lines. The system may further include a routing crossover of the positive signal line and the negative signal line of the second pair of signal lines, to decrease signal crosstalk between the first and second pairs of signal lines. The routing crossover may include at least one of the AC caps.
