This devices uses a 2.5-V supply for the whole device. This device does not have internal LDOs, so it is important that this device is connected to a low noise supply that does not have excessive spurious noise. A direct connection to a switching power supply will likely result in unwanted spurs at the output. Bypassing can be done individually at all the power pins, and TI recommends to have a capacitor suitable for higher frequency on the top layer so higher-value capacitors more suitable for lower frequencies can be farther away. The supply pins for the clocks and the LOGICLK should be isolated with a small resistor or ferrite bead if both are being used simultaneously. See the Section 5 section for additional recommendations for each pin.
