When a DLL is correctly locked, the total delay of the delay line should equal one period of the reference clock ? or it can be two or more reference clock cycles ? regards, Jef

As I read some paper showing their results regarding DLL, they said that after 10 or 14 cycles the DLL is locked. What is the reason, why it takes several cycles to locked the DLL?
