I an trying to use McBSP2, as an I2S Master, to send audio data to a STA333W digital audio system.
The STA333W device can use sample rates from 32 to 192 kHz. The McBSP supports sample rates from 8 to 48 kHz
I am trying to use 32kHz. What I cant figure out is how to setup the sample rate generator (SRG) for 32kHz operation.
At 32 bits per channel, with two channels at 32,000 Hz the bit clock should be 2048000. The FCLK used to drive the SRG is 96000000.
But 2048000 does not divide into 96000000 evenly. (47.875)
What am I missing here?
Thanks,
Larry
