Our application audio DAC need Master clock(MCLK) input. Like 2.8224Mhz/5.6448Mhz/11.2896Mhz(fs:44.1Khz) or 3.072Mhz/6.144Mhz/12.288Mhz(fs:48Khz)

And it request must be synchronized with I2S SCK / WS.

But currently we use CYW20706 only support below signal for audio DAC.

■ I 2S Clock: I2S SCK

■ I 2S Word Select: I2S WS

■ I 2S Data Out: I2S DO

Have anyone can provide suggestion or parts for our application?

Thanks,

Mitchell

hello:

Yes, 20706 seems no mclk output ,  we usually to test with two ways:

1. add an external mclk

2. choose a codec which do not need the mclk .

if you can upload the spec of the codec, we can help the check.

2. The codec is integrate solution with amplifier, we must to use it, so no other choice.
