USER’S GUIDE
Chapter 4. Configuration Options
This chapter lists several configuration options that can be setup with the EVB-
LAN9360. Possible configuration options are as follows:
• Listener and/or Talker with On-Board Codec
• Listener and/or Talker with External Codec/DSP
• Talker with On-Board MEMS Mic (PDM) and Listener with On-Board Codec
• Talker with On-Board MEMS Mic (PDM) and Listener with External Sink
• Talker with External PCM Source and Listener with On-Board Codec
• 1PPS Method for Clock Accuracy Measurement
Common jumper settings
For all configuration options, the following jumper settings are common:
Deviating jumper settings are described in the respective configuration sections, see
the following pages.
Codec
The on-board codec is configured by the LAN9360 via I
2
C.
Media clock generation
For media clock generation the following conditions apply:
• If an on-board source or sink is used, the media clock (FSY, SCK) is generated by
the LAN9360.
• If a MEMS microphone (PDM), either on-board or external is used, the media clock
(FSY, SCK) is generated by the LAN9360.
• If an external source or sink (codec, DSP) is used, the media clock can either be
provided externally or is generated by the LAN9360.
