SPDIF data is sent using bi-phase marking code. When encoding, the SPDIF data signal is modulated by
a clock that is twice the bit rate of the data signal.

On cases where SDMA TAP is put in the chain, the max. TCK frequency is limited by max. ratio of 1:8 of SDMA core frequency
to TCK limitation. This implies max. frequency of 8.25 MHz (or 121.2 ns) for 66 MHz IPG clock.
