Him Daniel,
the chip all 74HC4046, HC7046 and the HC9046 are well designed and 
working fine for the application for which they were designed for, but 
of course if you trying to used for something else you may run into 
problems. Roland best describes the funtion of the chip in details with 
many 
examples:http://books.google.com/books/about/Phase_Locked_Loops_6_e_Design_Simulation.html?id=WjNy3RX9xcAC
