4.4 TALKER WITH ON-BOARD MEMS MIC (PDM) AND LISTENER WITH
EXTERNAL SINK
In this configuration the LAN9360 acts as Talker and Listener. The on-board MEMS
microphone is used as PDM source. An external codec/DSP is connected to the Audio
Interface A Connector (J28, see
Section 3.2.5 ) as PCM sink.
Table 4-5 gives an overview of the jumper settings for this configuration.
Figure 4-4 depicts the jumper settings on the EVB-LAN9360.
The audio source (mono) for the AVB Talker is the on-board MEMS microphone
ICS-41350 as shown in
Figure 4-4 (upper left corner).
The audio sink for the AVB Listener is provided at Audio Interface A.
