The power supply must provide a constant voltage with a 10% maximum variation of the nominal value, and has to be able to provide at least 3 mA for the HD3SS6126 only (based on the maximum power consumption). It is also possible to provide the power supply from VBUS from the Host, just by including a voltage regulator powered through VBUS. Each V_CC pin must have a 0.1-µF bypass capacitor placed as closely as possible. TI recommends including two extra capacitors in parallel, which should be also placed as closely as possible to the V_CC pin. The suggested values for these extra capacitors are 1 µF and 0.01 µF.
