TPA3128D2: Output phase variation

Hi Derek,

Thank you for your explanation.

Could we estimate maximum device by device output phase(or output delay?) variation when I inputted exactly same signal?
I can accept design or target spec for this. Moreover, we never require to guarantee for this answer.

This is because, we plan to use this device for output phase sensitive application.

Hi Derek,

As far as my understanding, you are explaining about output switching signal phase delay.
However, I'd like to confirm about whether their is phase variation of output signal which is after the LC filter between 2 devices when using actual same input signal and circuit as follows.

Our expectation is both outputs are black line which is completely synced.  However, output would be red or blue if there is any internal portion which is adding any delay or variation to output side.
Is their such a internal circuitry?

Hi Derek,

This is just confirmation that your answer mean there isn't any portion which is causing device to device input-output propagation delay variation. Is it correct?
