ADAU1467 no data signal on SDATA_OUT3
Thread Summary
The user is experiencing an issue with no data signal from Serial Output Port 3 (pin 60) on the ADAU1467, despite BCLK and LRCK being present. The final answer suggests checking the DAC and hardware connections, as the project works fine for the support engineer. The settings for Port 2 and 3 are identical, and the issue is likely hardware-related.AI Generated Content
Hello All,
I'm struggling to get a signal from the Serial Output Port 3 of the ADAU1467.
BCLK and LRCK are present but no DATA... (pin60)
I have verified the connections to the chip, checked my DAC on port 2 of the 1467 and all seems to be OK.
Also the settings in SigmaStudio for Port 2 and 3 are the same. (both set as master and using clock domain 1)
Still all ports are working except for SDATA_OUT3.
A friend of mine has the same issue so I don't expect the chip to be failing.
The project file is attached.
(SigmaStudio v4.6)
Maybe someone could have a look?

Hello ODJ,
I tried the project which you have attached here. I am not able to reproduce the issue as you mentioned.It is working fine for me and I am getting data signals from SOUT 3.
We suggest you to check your DAC and verify the hardware connections.All the Serial ports are designed identically.There is very less possibility of one is working fine and another is not. And your project is working fine for me. I guess, as you are designing a custom board ,Kindly check your connections with DAC and the processor.
