1.0 English

With comparable or improved signal fidelity, the flexibility offered by the diamond jog breakout structure allows for significantly reduced crosstalk by having the option of moving signal vias further away from noise producing vias. The diamond jog’s ability to perform PCB level P-N swaps enables the reduction of routing complexity, such as loopback or crossovers, as well as provides greater area utilization of the available PCB real estate. This structure can be used for BGA breakouts throughout a PCB design. This structure was analyzed and can be used at data rates up to 28 Gb/s.
