configuring the sampling rate of tlc320ad535?

Started by pwoloszyn August 7, 2002
Hello,
I am using the TMS320C6211 DSP starter kit which has an on board
codec (the tlc320ad535). The codec's max sampling rate is 11.025khz,
but i would like to configure it for 8khz. How do i do this? I know
that i must set MCLK to 4.096Mhz to satisfy the equation fs =
MCLK/512 specified in the tlc320ad535 datasheet. But how do i change
MCLK? What is MCLK connected to?
Thanks in advance,
Peter.




Dear Pwoloszyn,
the default DSK sampling rate configuration is 8 KHz only.
just check it out. The sampling rate in this starter kit cant be changed
by the software, it is hardwired on the starter kit board.
U cud refer to the manual of TLS320AD535.

bye

Peter-

If you look at the DSK C6211 schematics that come with the board, you will see
that
the codec is already sampling at 8 kHz. It's a fixed rate board, and the
sampling
rate is not software-programmable.
