    Hi Nat,

    To give you the best recommendation I will need to know more about the inputs and output. Will the inputs be input with the same bit clock, frame clock and master clock? Will the output be working with the same clocks as the inputs?

    If these inputs were originally analog we have an analog part the PCM186X that can mix up to 4 analog inputs along with a digital input. Another option with the PCM186X is if the inputs can be on a single TDM bus, the mixer could mix the PCM streams into one output.

    Dear Justin
    The inputs are the same bit clock, frame clock and master clock. And the output is working with the same clocks as the inputs.
    Thank you~

    Hi Nat,

    It seems for the 186X, it will only be able to take in two channels, or one I2S input so your solution might not be possible with the PCM186X. Another part we have is the TAS5548 or TAS5558, this is an 8 channel input device over I2S that is mainly a PWM output but can mix the inputs together to output an I2S stream.
