Abstract:
An improved multi-layered ceramic package comprises: a plurality of signal layers, each having one or more signal lines; a plurality of vias, each providing one of a voltage (Vdd) power connection or a ground (Gnd) connection; at least one reference mesh layer adjacent to one or more signal layers; and a plurality of via-connected coplanar-type shield (VCS) lines, with a first VCS line extending on a first side of a first signal line within the plurality of signal layers and a second VCS line extending on a second opposing side of the first signal line. Each of the plurality of VCS lines interconnect with and extend past one or more vias that are located along the directional path in which the VCS lines runs. The placement of the VCS lines relative to the signal lines reduces coupling noise and controls impedance discontinuity in the ceramic package.
