Hello everybody,

I have a 100 MHz LVCMOS clock signal, and I need to adjust it phase shift (signal delay) smoothly in 10ns range.

I have already tried to solve this problem the easy way by using a cascade of inverters and R-C circuits between them. Unfortunately, each cascade gives about 1 ns phase shift adjustment and strong signal distortions (hex inverters are not fast enough, faster are not available).

Could you advise me any AD product to solve this problem?

Thanks.

It seems ad9512/13/14 could be the chipest solution of this problem. I will check.
