The Benchmark uses an AD1896 and upsamples asynchronously, the incoming clock is not used at all beyond the AD1896, there's a local clock that totally determines the jitter performance at the DAC. Everything is upsampled to 110kHz then fed to an AD1853 DAC, the ASRC acting as the de-jitter process. Of course the internal clock has to be low jitter (which it appears to be, from the measurements I've seen). Andy. -- Andrew L.
