When SDIF WCLK IN is used as a sync source, in and out are related as
below. The lower waveform is the output, the upper one is the input.

For
44.1 kS/s, out leads in by about 500 ns, and for 96 kS/s it is about 230 ns.
Figure 23 – Wordclock in to Wordclock out, 96 kS/s
Figure 24 – Wordclock in to Wordclock out, 44.1 kS/s
If tighter alignment of WCLK IN to WCLK OUT is needed, consider using a
dCS 992 Master Clock, where the phase of individual word clock feeds is
adjustable, or contact us.
