    B --> M

The EVB-LAN9360, assembled with one stereo audio codec, can be used stand-alone to directly test or implement several configuration options (e.g., the board operates as a Talker and uses the Line In of the on-board codec).

Apart from the stand-alone use case, the board can be easily extended with customer components via on-board expansion connectors that allow external devices to be connected.

If the board should be run in stand-alone operation or if it uses external components can be configured by jumpers (simplified depicted in Figure 1-2; configuration details can be found in Figure A-1.

In addition, the EVB-LAN9360 supports an four MEMS microphones application use case that can be simulated via an external board. Details are described in Appendix B, Four Microphone Add-On Board.

The LAN9360 I²C Service can be used to remotely control local I²C peripherals via the I²C Service Add-On Board. For details see Appendix C, I²C Service Add-On Board.

Chapter 2. PHY Daughter Board

As shown in Figure 1-1, the EVB-LAN9360 is designed in a way that allows to easily exchange the Ethernet transceiver (PHY) and connector. For this purpose Microchip Technology Inc. provides LAN PHY daughter boards:

• For 100BASE-TX applications the LAN PHY daughter board uses a KSZ8041 ^1 ; for details refer to https://www.microchip.com/Developmenttools/ProductDetails/AC320004-5
• For 100BASE-T1 applications the LAN PHY daughter board uses a LAN8770 [1]; for details refer to https://www.microchip.com/Developmenttools/ProductDetails/EV48S68A
• For 10BASE-T1S applications the LAN PHY daughter board uses a LAN8670; for details refer to https://www.microchip.com/en-us/development-tool/EV06P90A

LAN PHY daughter boards must be connected to the EVB-LAN9360 by use of J2-J5, see Section 5.1.

Note: Connecting or changing LAN PHY daughter boards is only permitted when the device is detached from power. Hot plug is not supported and could damage the hardware.

Note: Repeated plugging and unplugging of LAN PHY daughter boards should be avoided due to the sensitivity of the connectors.

Figure 2-1 shows some examples of available LAN PHY daughter boards.

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 I²C.

Note: The configuration of an external codec is not included in the LAN9360's functionality.

Media clock generation

If an external source or sink (codec, DSP) is used, the media clock can either be provided externally or is generated on-board.

4.1 TALKER/LISTENER WITH ON-BOARD CODEC

In this configuration the on-board codec is used as PCM source and sink.

The media clock may be recovered from the network with the PLL or generated onboard (selected by LAN9360 configuration options Clock Source and property Clock-Mode).

Table 4-2 gives an overview of the jumper settings for this configuration.

The audio sink for the AVB Listener is provided at Audio Interface A.

The AVB Talker receives the audio signal (stereo) through the blue jack connector (Line In).

4.5 1PPS METHOD FOR CLOCK ACCURACY MEASUREMENT

In this configuration the LAN9360 does not process audio data, neither as a Talker nor as a Listener—hence, jumper settings are not required.

A one-pulse-per-second (1PPS) signal is provided at J22/Pin1 to measure the accuracy of the synchronization to the gPTP clock. The device may operate as gPTP master or gPTP slave. Reception of a media clock is not required and has no influence on the 1PPS signal.

Figure 4-5 indicates the location of J22/Pin1 on the LAN9360 Development Board.

To evaluate the 1PPS signal, an oscilloscope can be connected to J22/Pin1.

It is of advantage to compare the 1PPS signals with multiple devices (gPTP master with several gPTP slaves).

Appendix B. Four Microphone Add-On Board

This chapter describes a use case with four digital MEMS microphones that are available on an external circuit board, the so-called Four Microphone Add-On Board (AIS21016).

The Four Microphone Add-On Board in combination with the EVB-LAN9360 can be used to produce an AVB Stream containing up to four audio channels, each captured from one of the four microphones.

Typical areas of application are:

• Mono microphone (one channel)
• Stereo microphone (two channels)
- Microphone array (three or four channels), e.g., to realize beamforming applications

A picture of the Four Microphone Add-On Board is shown in Figure B-1.

FIGURE B-1: FOUR MICROPHONE ADD-ON BOARD

This chapter provides an explanation on the practical utilization of the LAN9360 I²C Service to remotely control local I²C peripherals by using the so-called I²C Service Add-On Board (AIS23008).

The I²C Service Add-On Board in combination with the EVB-LAN9360 can be used to test and validate the usage of the LAN9360 I²C Service either through the sample code library provided by Microchip or through the customer's own implementation.

The following peripherals are available on the I²C Service Add-On Board:

• Weather sensor
• Ambient light sensor
  • GPIO expander with four LEDs (outputs) and four DIP switches (inputs)

A picture of the I²C Service Add-On Board is shown in Figure C-1.
