The CS42528 will auto-detect the AES format of the incoming S/PDIF stream and display the infor-
mation according to the following table.
This bit identifies the source of the internal system clock (MCLK).
The CS42528 detects the ratio between the OMCK and the recovered clock from the PLL. Given the
absolute frequency of OMCK, this ratio may be used to determine the absolute frequency of the PLL
clock.
If a 12.2880 MHz, 18.4320 MHz, or 24.5760 MHz clock is applied to OMCK and the OMCK_FREQX
bits are set accordingly (see
of the PLL clock is reflected in the RCVR_CLKX bits according to
of the PLL clock does not match one of the frequencies given in
closest available value.
If the frequency of OMCK is not equal to 12.2880 MHz, 18.4320 MHz, or 24.5760 MHz, the contents
of the RCVR_CLKX bits will be inaccurate and should be disregarded. In this case, an external con-
troller may use the contents of the OMCK/PLL_CLK ratio register and the known OMCK frequency to
determine the absolute frequency of the PLL clock.
