DS90UB953A-Q1: EMI solution for Camera SERDES

Hi team,

I searched EMI solution in e2e forum.

and found EMI solution by using SSC OSC at DES side under synchronous mode.

but BU answered AON also shows improvement because it works like "pseudo spread"

Even I google it, I cannot find mechanism what pseudo spread is.

Could you pls help me understand what it is??

then I can explain to customer when I suggest option for EMI solution .

Thanks
