4.3 TALKER WITH ON-BOARD MEMS MIC (PDM) AND LISTENER WITH
ON-BOARD CODEC
In this configuration the LAN9360 acts as Talker. The on-board MEMS microphone is
used as PDM source. In addition, the LAN9360 may act as Listener. The on-board
codec is used as PCM sink.
Table 4-4 gives an overview of the jumper settings for this configuration.
Figure 4-3 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 4-3 (upper left corner).
The AVB Listener plays the received audio signal (stereo) through the green jack con-
nector (Headphone Out).
