Does the xcore support multiple I2S datelines with common bc

Post by Kasebe »

I have a question for I2S operation.

 

[I2S Input]

BCLK

LRCLK

SDATA

x4

[I2S Output]

BCLK

LRCLK

SDATA0

SDATA1

SDATA2

SDATA3

x1


 

Generally, I think 1ch I2S has 3 line.

Can X-core operate 4 data output with common BCLK and LRCLK?

Thank you.

No, 2 channels i.e. stereo.

Yes it can. The current I2S component assumes on BCLK and LRCLK for multiple ADC/DAC datalines.

You can of course program the xcore do what ever you like!
