11 / 20 page AD1882A Rev. 0 | Page 11 of 20 | August 2008 DIGITAL MICROPHONE INTERFACE TIMING SPECIFICATIONS The digital microphone interface can support one or two digital microphones using two or three codec pins. Both uniplex (one microphone per data pin) and multiplex (two microphones sharing the same data pin) are supported. The timing for these configurations are shown in Figure 3 and Figure 4. The interface can generate a microphone clock at 1.5 MHz, 2.0 MHz, or 3.0 MHz to suit quality and power requirements. Table 7.
