10 Power Supply Recommendations

The ONET1130EC is designed to operate from an input supply voltage range between 2.37 V and 2.63 V. To reduce transmitter and receiver power supply coupling, as well as digital coupling into the analog circuitry, there are separate supplies for the transmitter, receiver and digital circuitry. VCC_TX is used to supply power to the transmitter, VCC_RX is used to supply power to the receiver and VDD is used to supply power to the digital block. Power supply decoupling capacitors should be placed as close as possibly to the respective power supply pins.
