Precise phase shifter on existing sinusoidal signal under 1MHz

Hello,

I need to design a precision phase shifter capable of generating an output signal identical in amplitude and frequency with a sinusoidal input signal, but phase shifted in the 0 to 360° range. I am searching any IC that can help in this design.

Unfortunately I cannot use DDS because I need to act on an existing signal, not to generate a signal and its phase-shifted replica.

Frequency is up to 1MHz.

Since phase setting should be precise, I don't have anything against using a software interface to set the phase, although a simple DAC or potentiometer is good as well.

Any suggestion and/or target IC to help the design ?

Many thanks in advance,

Marco
