Power Supply Recommendations

0.1 µF capacitors are recommended to be placed very close to V3P3Vx pins to GNDx. 1-µF capacitors are recommended to be placed placed very close to VBUSx pins to GNDx.

These decoupling capacitor recommendations are irrespective of whether the 3.3 V supplies are provided externally or generated using internal LDOs.

Refer to the Section 11.1.1 section for recommended placement of the decoupling capacitors. Small footprint capacitors (0402/0201) are recommended so that these may be placed very close to the supply pins and corresponding ground pins on the top layer without the use of vias.

While isolating a host/hub or bus-powered peripherals, isolated power is needed and can be generated with the help of a transformer driver such as TI's SN6505B. For such applications, detailed power supply design, and transformer selection recommendations are available in the SN6505 Low-Noise 1-A Transformer Drivers for Isolated Power Supplies data sheet.
