How to impliment a lock detector with programmable lock detect window?

[Death]

Could anyone suggest me how to impliment a lock detector with programmable lock detect window...
ie
bit1 - 2ns (diff bt ref and feedback clk) o/p of lock detect = lock
bit2 - 4ns (diff bt ref and feedback clk) o/p of lock detect = lock

any reference links will be of great help..

Hi
2ns is diffcult to control, you can use delay line to open the window.
