Notes: 19.
If Fs is lower than 46.875 kHz, the maximum CCLK frequency should be less than 128 Fs. This is
dictated by the timing requirements necessary to access the Channel Status and User Bit buffer
memory. Access to the control register file can be carried out at the full 6 MHz rate. The minimum
allowable input sample rate is 8 kHz, so choosing CCLK to be less than or equal to 1.024 MHz should
be safe for all possible conditions.
Data must be held for sufficient time to bridge the transition time of CCLK.
For f

<1 MHz.
