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.
