These two bits, along with the UNLOCK bit in register
on page
are set to '00'b, selecting the output of the PLL as the internal clock source, and the PLL becomes
unlocked, RMCK will equal OMCK, but all internal and serial port timings are not valid.
When the FRC_PLL_LK bit is set to ‘1’b, the SW_CTRLX bits must be set to ‘00’b. If the PLL becomes
unlocked when the FRC_PLL_LK bit is set to ‘1’b, RMCK will not equal OMCK.
This bit is used to enable the PLL to lock to the ADC_LRCK with the absence of a clock signal on
OMCK. When set to a ‘1’b, the auto-detect sample frequency feature will be disabled and the
SW_CTRLX bits must be set to ‘00’b. The OMCK/PLL_CLK Ratio (address 07h) (Read Only) register
contents are not valid, and the PLL_CLK[2:0] bits will be set to ‘111’b. Use the DE-EMPH[1:0] bits to
properly apply de-emphasis filtering.
This register allows the user to find the exact absolute frequency of the recovered MCLK coming from
the PLL. This value is represented as an integer (RATIO7:6) and a fractional (RATIO5:0) part. For
example, an OMCK/PLL_CLK ratio of 1.5 would be displayed as 60h.
