100 Mhz LVCMOS clock signal smooth phase shift

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.
