The digital microphone interface permits connection of a digital microphone(s) to the CODEC via the
DMIC0, DMIC1 (48QFN package only), and DMIC_CLK 3-pin interface. The DMIC0 and DMIC1 sig-
nals are inputs that carry individual channels of digital Mic data to the ADC. In the event that a single
microphone is used, the data is ported to both ADC channels.
The DMIC_CLK output is controllable from 4.704Mhz, 3.528Mhz, 2.352Mhz, 1.176Mhz and is syn-
chronous to the 24Mhz internal clock. The default frequency is 2.352Mhz.
92HD75B supports the following digital microphone configurations:
