Crosstalk cancellation for signal lines

A method, comprising:

• transmitting a first signal via a first signal line of a set of signal lines;
• transmitting a second signal via a second signal line of the set of signal lines;
• and
• transmitting a third signal via the second signal line, the third signal for combining with a fourth signal on the second signal line to obtain a fifth signal via the second signal line with a lower amplitude than each of the third signal and the fourth signal, and the fourth signal based at least in part on the first signal and a capacitance between the first signal line and the second signal line.

An apparatus, comprising:

• a first ground plane extending in a first direction;
• a second ground plane parallel to the first ground plane;
• a set of signal lines extending in the first direction between the first ground plane and the second ground plane;
• and
• circuitry configured to:
• transmit, to a first receiver, a first signal via a first signal line of the set of signal lines;
• transmit, to a second receiver different than the first receiver, a second signal via a second signal line of the set of signal lines;
• and
• transmit a third signal via the second signal line, the third signal for combining with a fourth signal on the second signal line to obtain a fifth signal via the second signal line.
