is there any ripple noise spec requirement for GMSL PoC power supply?

POC source should be filtered before coupled into GMSL path. Theoretically the noises should be eliminated to protect GMSL signals from disturbance.

Hi Mason,

thanks for your answer , so we don't need concern about PoC power noise even the noise is 00mVp-p or higher , due the filter can eliminated the noise to protect GMSL signal correctly.

Yes, but that depends on the ripple frequency and your designed POC filter characteristics. The designer should be careful about this and make some simulation to verify your design.
