Abstract
Methods and apparatus for utilizing flexible (flex) circuit technology and/or axial cable to facilitate routing of high-speed data channels are described herein. Under one aspect, a high-speed data channel if routed between an integrated circuit (IC) and a high-speed data connector mounted to a multilayer printed circuit board as part of a circuit assembly. The circuit assembly includes a signal pathway providing a high-speed data channel from the integrated circuit to the high-speed data connector, wherein a portion of the signal pathway includes a flex circuit or axial cable.

-25. (canceled)
A circuit assembly comprising:
- a multilayer printed circuit board (PCB);
- an integrated circuit (IC) coupled to the printed circuit board;
- a high-speed data connector coupled to the printed circuit board, the high-speed data connector being disposed at a distance greater than 3 inches from the integrated circuit (IC);
- and
- a signal pathway coupled between the high-speed data connector and the integrated circuit, the signal pathway providing a high-speed data channel from the integrated circuit to the high-speed data connector having a bandwidth of at least 25 Gigabits per second (Gb/s), wherein a portion of the signal pathway includes a flexible (flex) circuit or axial cable having a length of at least 3 inches.
A method of routing signals for a high-speed data channel between an integrated circuit (IC) mounted to a multilayer printed circuit board (PCB) and a high-speed data connector mounted to the multilayer PCB, the method comprising:
- routing the signals from the IC to the high-speed data connector through a signal pathway supporting a bandwidth of at least 25 Gigabits per second (Gb/s), wherein a portion of the signal pathway includes a flexible (flex) circuit or axial cable having a length of at least 3 inches.
