The Sony/Philips Digital Interface (SPDIF) timing parameters are provided in
totally asynchronous, therefore there is no need for relationship with the clock.
differences between high-low and low-high propagation delay which is called the skew.
4.3
The Serial Audio Interface fully complies with the Industry standard Philips IIS (InterIC Serial Audio Bus)
timings.
