HI, Team

Customer prefer to use 2 pcs PCM5121 for 4 channel DAC, and they prefer use the same TDM interface for 2 PCM5121.

I suppose our device can't support that, do u have any suggestions?

Thanks.

    Hello, in general the possibility of interfacing 2 devices for a specific TDM depends on many factors and it can be possible for some combination of clk speed, word width and fs. Without these information it is not possible to say yes or no.

    We have 8 channel devices such as PCM1681 and PCM1690 as well as 4channel devices such as PCM4101 if they are interested in other devices.

    Regards,
