Hi folks,
I'm progressing a 4-way speaker design with dig. x-overs and DACs placed in each stereo speaker box. To feed them the digital signal, each Box is supposed to receive a coax stereo SPDIF signal sourced from a pre-processing DSP unit. The current (industrial) design only provides one (not reclocked) 75Ohm SPDIF Output using the SRC4382 TX+ signal from pin #32.
I want to do two things and am not certain if my implementation idea will work:
1. Reduce Jitter of the Output signals by reclocking (the TX+ output signal) with the available 24.576MHz low phase noise clock.
2. Feed the reclocked signal to two BNC-75Ohm koax outputs (one feeding each box).
So the question really is: (How) Can I do this with the TX+ signal from the SRC4382? I've read the data sheet and it seems as if the TX+ signal is TTL compatible, but I am still unsure if my idea would work:
Just for completeness: The sample rate is 48 or 96ks/s, the SPDIF input (driven by the buffer and a 75Ohm coax cable) has the same transformer in the input.
Thanks a lot for feedback, advice and recommendations!
