That's a quite widespread(or lets say broadband ;)) question - interesting play you're into.

As I understand you want to make a 1 bit SDR having PDM signal generated again from a 1-bit ADC. Now you want to mix it with a LO which was fine, but also want to take PDM signal as a mixing reference?

If wanting for a SDR, how about converting your PDM with a low-pass filter or a CIC filter in digital logic implementation.
