ABSTRACT:
For electrical backplanes and the like, a power plane adaptation to improve the propagation of high-speed signals through clearances in an embedded power plane is disclosed. In exemplary embodiments, the power plane is segmented in a high-speed connector region, such that a portion of the metal layer that forms the power plane is retained in the high-speed connector region—but isolated from the power-delivery portion of the power plane. The isolated portion is connected to digital ground, and clearances are formed therein where high-speed signaling throughholes will pass through the region. In some embodiments, various attainable advantages include better manufacturability, better matching and control of high-speed signaling throughhole impedance, and improved noise isolation. Other embodiments are described and claimed.
