Does the fact that my M-DAC (repeatedly) passes it's bit perfect test mean that there’s no jitter present in the signal transfer from the source to the DAC?

As I understand it, jitter is produced when there are problems with mismatches in the timing of arrival or processing of the packets of digital information – does the passing of the bit-perfect test mean that these are either not an issue or have been corrected?

Or am I simply misunderstanding what the bit-perfect test actually tests - i.e. that the file signal arriving at the DAC is absolutely identical to the one leaving the source?

The Bit perfect test tells you absolutely ZERO about jitter level I'm afraid...

Digital data recovery is deign to cope with significant levels of jitter before data is lost - on the lab bench we routinely over 20nS of random Jitter and Data is recovered bit perfect.

Also on the lab Bench I can introduce (or remove) a jitter spurie competent that's less then 1pS and its effects can be audible (depending upon the components spectral distribution) - that's more then x20000 times less then the level Bit perfect data recovery might fail...
