Searching the tutorials I couldn't find an example of how to use this type of boundary condition, so I've created a very small and simple tutorial. Basically, the setup requires the definition of 4 parameters:

   inlet
   {
       type oscillatingFixedValue;
       amplitude       0.5;
       frequency       0.2;
       refValue        uniform (1 0 0);
   }

The above setup enables to specify a boundary condition for an entire patch that varies in time as:

    $1+amplitude\cdot\sin\left(2\pi\cdot frequency\cdot t\right)$

Sample OpenFOAM case - it applies to Valid versions:
