An issue about  AD630

Dear Sir/Madam,

 

In former application, we used AD630 to phase lock. if the 4KHz is useful for us, we use 8 KHz( frequency-doubled )  square as reference  signal.

Now we want to use the  same frequency as reference signal to phase lock.  I wonder which chip could  achieve this function.

 

Thanks.
