Part Number: TLV320AIC3212


We intend to use TLV320AIC3212 in an IP Phone design (based on Sitara AM5728) with analog inputs & outputs, and connected to AM5728 on McASP2 as below:

In this case:

- how many AXR pins have to be connected between AM5728 and TLV320AIC3212?

- will single MCLK input from AM5728's CLKOUT2 be sufficient?

- will a single set of WCLK & BCLK (say WCLK1 & BCLK1) be sufficient?

  • Hello Thariq,

    a Single of each MCLK,BCLK, and WCLK is just fine. 

    I couldn't really comment on the AM5728s CLKOUT2 please ask that question in the processors forum. 

    best regards,

    Hello Steve,

    Thank you for the inputs regarding the clocks.

    What about the AXR lines from AM5728? Is it sufficient to connect just 2 lines to DOUT1 & DIN1 to support the above mentioned analog interfaces, or do we need to connect all 3 sets?

    Any processor questions would be better answered in the Processors forum.
