Connection of BLCK, LRCLK, SDATA_IN

Hi,

We understand that you are using ADSP-21569 SOM board. If so,

You can connect ADSP-21569 with AD2428WD1BZ using DAI pins.
Using SRU configuration you can route the SPORT Signals to DAI pins and then connect wires externally from the DAI pins to AD2428WD1BZ.

For example, if SPORT4A DATA0 is transferred to DAI1_01 pin: Below SRU configuration is used in the project.

SRU2(SPT4_AD0_O,DAI1_PB01_I); /* SPORT 4A to DAI1_01*/
SRU2(HIGH,DAI1_PBEN01_I); /* Configure pin buffers as signal output */
Then connect the P2.2 pin(DAI1_PIN01) on the EV-SOMCRR_BRKOUT to the SDATA_IN pin of the AD2428WD1BZ.

Please refer “EV-SOMCRR-BRKOUT” schematic from the below link:

Additionally, you can install BSP package for ADSP-21569 from the below path which have examples codes for peripherals:
download.analog.com/.../ADI_EV-2156x_EZ-KIT-Rel3.0.0.exe

After installation, please refer examples from the below path:
<installation path> \ADSP-2156x_EZ-KIT-Rel1.0.1\ADSP-2156x_EZ-KIT\Examples\drivers\adc

For more details, please refer chapter “22 Digital Audio Interface (DAI)” from the hardware reference manual:

Thanks.

I will study SRU configuration and TDM4 connection, ... etc. ^_^.
