TDAC1543 without re-clocking

TDA1543Rebekka_distortion

Supply voltage is 8 V. I/V resistors are 280 Ohm. DC at the output is adjusted to 1.8 VDC.

TDA1543Rebekka_Jitter

Jitter is 800 ps. Optical input.

TDA1543Rebekka_Jitter_coax

Jitter is 2800 ps. Coax input. I've got no idea why jitter is so high? The CS8412 input is done as explained in the Crystal datasheet.


TDAC1543 with Elso's reclocking

TDA1543_16fach_distortion

16 converter chips in parallel. Supply voltage is 8.5 V, I/V resistors are 137 Ohm and DC at the output is adjusted to 3.91 VDC.

TDA1543_16fach_jitter_coax

Very high jitter: 10500ps. This is much worse than the TDAC1543 without re-clocking, but it sounds significantly better. Here is some more interesting info on jitter and re-clocking: https://www.diyaudio.com/forums/showthread.php?s=&threadid=28302
