PLL or XTAL is a choice of parents. They are not dependent to each other (direct citation): The source of the frequencies can be XTAL or PLL, depending on the configuration. Any of the two available frequencies can be selected for each of the platform clocks. According to datasheet on hand CherryTrail has them, though they both provide 19.2MHz frequency.
