How to define clock generated by the other clock?

Thanks a lot for your answer. In the Altera Max 2 Kit is given the possibility to use a digital PLL named as 72497 and can be found easily at the Library others/maxplus2/74297. The fact is that using this chip is a bit difficult for me because i actually see many Pins and it's a bit terrifying to me. I have still downloaded the datasheets of the 74297 but there are still many issues and many things such as Phase 1 , Phase 2 , Phase B and so on....Any friendly advice with that?
