A connector includes pins having a pinout including a functional designation cadence. The functional designation cadence includes a first ground pin, a first signal pin, a no-connect pin, a second signal pin, and a second ground pin, where the first signal pin is positioned between the first ground pin and the no-connect pin, the no-connect pin is positioned between the first and second signal pins, and the second signal pin is positioned between the no-connect pin and the second ground pin. Alternately, the functional designation cadence includes a first ground pin, a first signal pin, a third ground pin, a second signal pin, and a second ground pin, where the first signal pin is positioned between the first and third ground pins, the third ground pin is positioned between the first and second signal pins, and the second signal pin is positioned between the third and second ground pins.
