Hi,
I am using altera IP core PLL with the setup shown in the image.
When I check the waveform in the scope, I have got a sine wave of 2 vpp with a DC component of 1.5 v. The issue here is that am using that clock to sync with the Audio codec WM8731 for I2S communication but it seems that the codec is not understanding that clock waveform. Not sure if this is the right way to send the BCLK to the codec or definitively I need an external circuit. I checked the I2C commands to activate the digital audio interface and all commands have been acknowledge correctly and checked through the scope. Please let me know your thoughts.
