Direct connection of high speed signals on PCB chip
Abstract:
To eliminate signal loss and sources of signal attenuation, a connection methodology is utilized which enables high-speed signals to be directly communicated from particular integrated circuits housed on a printed circuit board, to other locations within a system. More specifically, a signal escape strategy directly connects a high-speed cable to a point on the circuit board which is very close to the integrated circuit itself. A back-side connection methodology is utilized so that electrical signals pass directly from the integrated circuit through a via, to a connection point on the backside of the circuit board. To accommodate this connection, a specially designed interposer and related paddle cards are utilized so the high-speed communication cable can be easily attached.
