5.7.2
OMCK FREQUENCY (OMCK FREQX)
Default = 00
Function:
Sets the appropriate frequency for the supplied OMCK.
5.7.3
PLL LOCK TO LRCK (PLL_LRCK)
Default = 0
0 - Disabled
1 - Enabled
Function:
When enabled, the internal PLL of the CS42426 will lock to the LRCK of the ADC serial port
(ADC_LRCK) while the ADC_SP is in slave mode.
5.7.4
MASTER CLOCK SOURCE SELECT (SW_CTRLX)
Default = 01
Function:
These two bits, along with the UNLOCK bit in register “Interrupt Status (address 20h) (Read Only)”
on page 46, determine the master clock source for the CS42426. When SW_CTRL1 and SW_CTRL0
are set to '00'b, selecting the output of the PLL as the internal clock source, and the PLL becomes
unlocked, then RMCK will equal OMCK, but all internal and serial port timings are not valid.
5.7.5
FORCE PLL LOCK (FRC_PLL_LK)
Default = 0
Function:
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. The OM-
CK/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.
