Abstract

An electronic package including modulated mesh planes can reduce crosstalk between adjacent signal wires. Modulated mesh planes above and below a wiring plane include sets of adjacent wires arranged parallel to signal wires within the wiring plane, and sets of adjacent wires arranged perpendicular to the signal wires. The wires in each of the mesh planes are electrically interconnected and insulated from the signal wires by a dielectric layer. The electronic package also includes a region of the mesh planes having the adjacent wires that are perpendicular to the signal wires separated by a first distance, and another region of the mesh planes having adjacent wires perpendicular to the signal wires separated by a distance greater than the first distance. A set of rectangular mesh areas of the mesh planes can be populated with supplemental wires and via interconnect structures which can further reduce crosstalk.
