The CPU on BBB is powered by 3V3. This means all digital output (GPIO, PWM, ...) will be at 3V3 as well.
In order to get a 5V pulse train, you'll need an external driver. I use darlington arrays for that purpose, like ULN2804 <http://html.alldatasheet.com/html-pdf/55062/ALLEGRO/ULN2804/246/1/ULN2804.html> .
