tlv320aic3104 connection to AM3517

Other Parts Discussed in Thread: TLV320AIC3104, AM3517

Hello!

I'm working on a design to use the tlv320aic3104 codec in connection to AM3517 processor.

Here what I have:

1) 12MHz oscillator is used as the MCLK source for tlv320aic3104

2) MCLK is connected through 22Ohm resistor to the MCBSP_CLKS line at am3517

3) MCBSP2 is used for I2S at am3517

My question is about if I should connect 12MHz to the the MCBSP_CLKS line at am3517 or not? Does it depend on what mode (master/slave) aic is used?

Please help!

    The connection is not required, but certainly is an option.  The mcbsp_clks signal is used in the sample rate generator block within the MCBSP peripherals.  The mcbsp_clks is common amongst all of the instantiations of the MCBSP in the AM3517 so if you need another sample rate reference clock, perhaps you would be better served connecting it to this other clock.  I don't know if that is a need for you, but wanted you to be aware.  As I mentioned, it is fine to connect the MCLK to the mcbsp_clks signal.

    The use of mcbsp_clks for the sample rate generator is independent of master or slave.  Although the use of the internally generated timing signals by the sample rate generator is dependent on mode.
