USB PLL configurator

Recommended Posts

I made a simple calculator with XT2 as input and USBPLLDIVB as output, for configuring USB PLL. Some calculated values are in Table 38-2 "Register Settings to Generate 48 MHz Using Common Clock Input Frequencies" of slau208 "MSP430x5xx MSP430x6xx Family User's Guide".


USB spec defines the tolerance as +/- 0.25% (2500 ppm) for full-speed bus.
