We seem to be talking about two different things. I am talking about what some people call "Clock Link". The master clock is in the DAC box. It feeds the DAC chip directly. A copy of this clock is sent upstream to the transport box. The incoming data stream from the transport is reclocked by the master clock in the DAC box.A block diagram of this is linked below.
If the cables between the two boxes are optical cables, it would seem that there is no way for any jitter from the transport to make it past the re-clocking module (FIFO) in the DAC box.
Please give a plausible explanation for how jitter from the transport makes it to the DAC chip in this case.
