TLV320AIC3120EVM-U: How to change MCLK using GUI.

Part Number: TLV320AIC3120EVM-U
Other Parts Discussed in Thread: TLV320AIC3120


On TLV320AIC3120 EVM, my customer confirmed to operate audio input/audio output correctly on default setting.  However, on application GUI, he can not change the MCLK frequency.  He seems to keep same frequency : 12MHz.   Could you please let us know how to change the MCLK?  Please advise us.

Thanks and best regards,

  • Hello M. Hattori,

    The EVM is supplied a fixed MCLK and cannot be changed within the GUI. The customer will need to use an external MCLK. To use an external MCLK, they will need to cut some traces on the board as this EVM does not have the option for an external ASI.
