ALC892 datasheet 7.1+2 channel hd audio codec with content protection 80 track id: jatr-2265-11 rev. 1.2 11.2. digital microphone implementation this section describes the ALC892 digital micr ophone implementation. there is one clock output pin and 1 data input pin in the ALC892. the ALC892 pr ovides the clock signal to the digital microphone. when the digital microphone receives the external sound i nput, it converts the anal og signals to digital in a 1-bit format. the 1-bit data is de livered to the codec though the data input pin. the digital filter in the audio codec converts the 1-bit data stream into puls e code modulation (pcm) data . the pcm data is sent to the hda controller through the hda link. figure 22. digital microphone implementation the ALC892 supports a two-wire interface for the digital microphone and operates in single-channel (mono type) or stereo-channel mode. one pin is clock output to the digital microphone, and the other is a serial pin. the default clock output is 2.048mhz. the ALC892 uses one data pin to support stereo inputs from various digital microphones and microphone module. popular digital microphones provided from fortemedia, akusti ca, knowles, and hosiden are supported. please contact realtek and your digital microphone vendor to get the best compatibility between the ALC892 and vari ous digital microphones. figure 23. stereo digital microphone connection www.datasheet.co.kr datasheet pdf - http://www..net/
