Note: The WM8918 is a 24-bit device. If the user operates the WM8918 in 32-bit mode then the 8
LSBs will be ignored on the receiving side and not driven on the transmitting side. It is therefore
recommended to add a pull-down resistor if necessary to the AIFRXDAT line and the AIFTXDAT line
in TDM mode.
BCLK FREQUENCY
The BCLK frequency is controlled relative to SYSCLK by the BCLK_DIV divider. Internal clock divide
and phase control mechanisms ensure that the BCLK and LRCLK edges will occur in a predictable
and repeatable position relative to each other and relative to the data for a given combination of DAC
sample rate and BCLK_DIV settings.
BCLK_DIV is defined in the “Digital Audio Interface Control” section. See also the “Clocking and
Sample Rates” section for more information.
