Hi,
we are not using TV, PCIe and SATA interfaces in our design. Is it necessary to give filtered supply to these pins(power pins are listed down) or a normal digital supply will do? I want to mention that we are designing a highly dense and complex board. addition of one capacitor also can create many complexities. In EVm they have not used a ferrite bead. One inductor has been used and I believe since its a switching regulator inductor at the output is necessary.
