In general, the BitClockFrequency (BCLK) is calculated by the following expression:
BitClockFrequency=(DataWordBit +1) × SamplingFrequency

1. It is recommended to reserve RC (e.g. R=22Ω, C=22pF) circuit on the PCM lines, especially for
PCM_CLK.
2. UG96 module provides a digital clock output (CLK_OUT) for an external audio codec, the CLK_OUT
function is disabled by default. When CLK_OUT is required, AT command is used to provide the
codec with a 13/26MHz clock generated from the module. Refer to document [1] for details. If
unused, keep this pin open.
3. A RC (e.g. R=22Ω, C=47pF) circuit is recommended to be reserved on CLK_OUT line. If external
audio CODEC is MAX9860 or NAU8814, the RC circuit should be mounted, if it is ALC5616, then it is
not mounted.
