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,
