You didn't state how much delay you are getting and how much you can tolerate. If you use a fast logic device, you can probably achieve your goal. I believe 74Sxx or 74Hxx device should suffice. If you need closer to zero delay, feed your source through an inverting gate and a non-inverting gate which should give you satisfactory results.

Now, putting the signal through an inverter causes a small time delay leaving the two signals to not be exactly 180 degree out of phase.  I imagine this is a common problem and suspect an inverter with matched buffer IC exists that allows you to reduce this error.  Does such an IC exist? Can anyone give me a part number? (I was suprised to find my search of Digikey turn up nothing, but I'm not sure exactly what to search for)
