Hi Sir

We would like to C6746 for development. And we have four Mic input ( the interface is I2S).

Which interface of C6746 should we prefer to use so that we can connect to 4 Mics? MCASP or MCBSP

Any reference design or checklist we should know ?

please advise

Hi Yimin,

There are various solutions to connect 4 microphones to C6746 based board but I suggest you some resources about PCM1864 4-Channel Software-Controlled Audio ADC which can be connected via McASP.
You can use for reference design TMDSLCDK6748 and TIDEP-0088 boards. You can find technical documentation including schematics and training materials at:
