10.1 TUSB2046x Power Supply
VCC should be implemented as a single power plane.
- The VCC pins of the TUSB2046x supply 3.3-V power rail to the I/O of the TUSB2046x. This power rail can be isolated from all other power rails by a ferrite bead to reduce noise.
- All power rails require a 10-μF capacitor or 1-μF capacitors for stability and noise immunity. These bulk capacitors can be placed anywhere on the power rail. The smaller decoupling capacitors should be placed as close to the TUSB2046x power pins as possible with an optimal grouping of two of differing values per pin.
