Figure 23. Audio Clock Generation Processing
The part can accept an MCLK input from 512 kHz to 50 MHz, which can then be passed through either a
programmable divider or a PLL, to get the proper internal audio master clock needed by the part. The BCLK
input can also be used to generate the internal audio master clock.
A primary concern is proper operation of the codec at various sample rates with the limited MCLK frequencies
available in the system. This device includes a highly programmable PLL to accommodate such situations easily.
The integrated PLL can generate audio clocks from a wide variety of possible MCLK inputs, with particular focus
paid to the standard MCLK rates already widely used.
When the PLL is disabled,
Fsref = CLKDIV_IN / (128 × Q)
Where Q = 2, 3, …, 17
CLKDIV_IN can be MCLK or BCLK, selected by register 102, bits D7-D6.
NOTE – when NDAC = 1.5, 2.5, 3.5, 4.5, or 5.5, odd values of Q are not allowed. In this mode, MCLK can be as
high as 50 MHz, and Fsref should fall within 39 kHz to 53 kHz.
When the PLL is enabled,
Fsref = (PLLCLK_IN × K × R) / (2048 × P), where
P = 1, 2, 3,…, 8
R = 1, 2, …, 16
