AD1836 codec

Hello everyone.

I'm using an BF533  EZKIT  board where the BF533 is connected to an AD1836 codec.

I communicate with the codec in I2S mode. The setup is as suggested in the examples (that is DBCLK , DLRCLK and all the SPORT0 clocks and frame syncs are driven from the codec's ABCLK, ALRCLK).

So at this point the data rate of the DAC stream is 48kHz.

I have not worked with codecs before and although I have read the codec spec I was not able to clearly answer myself a question. Though it is not clearly mentioned there (or I have missed it perhaps) it seems to me that data rate for the input stream into the codec should be 48ksamples/sec (or 96 - in direct relation with the MCLK)

Or is it possible to feed the DAC at other rates (44.1k, 32k)?

Thank you,
