Abstract
A package substrate is contemplated herein for reducing cross-talk for noise-sensitive signals. The package substrate includes noise-sensitive conductors adapted to receive the noise-sensitive signals. In one embodiment, the cross-sectional width of the noise-sensitive conductors is increased to reduce certain parasitic effects such as resistance and/or inductance. The package substrate also includes guard conductors which are arranged co-planar with and substantially parallel to the noise-sensitive conductors. A plurality of vias spaced equidistant from one another extends from a ground conductor to the guard conductors, providing a substantially uniform voltage across the guard conductors. The overall effect will reduce the inductive and capacitive cross-talk from neighboring signals and increase the signal integrity of noise-sensitive signals.
