    A very good way to reuse frequency doublers with 5/6 DRIXOs

     

     

    If you use a frequency doubler for a DSD DAC, beware of subharmonics mixing with sigma-delta idle tones,

    Then again, Andrea’s DSD DAC looks like a long FIRDAC. As such, it should be much less sensitive to this issue than the rather basic model I simulated.
