Personal Area Network
4.3
Several configurations are possible to supply power to the SX1441 and the associated XE1413 or CX72302 radio
chip. The paragraphs 4.3.1 and 4.3.2 below show two recommended examples for 3 and 1.8V supply.
All typical averaged values are measured at room temperature (20°C) using the XE1413 or the CX72303 Bluetooth
radio in a Class 2 (typ. +2 dBm) mode. A high frequency system clock of 13 MHz provided by the radio chip is
used. The default UART speed is 115 kbits/s.
4.3.1 3V Supply Configuration, Single 13 MHz Crystal Oscillator
The on chip voltage regulators supply VDD_DIG, VDD_PA, VDD_ANA, VDDIO, and VDDIO_DIG, as well as the
radio.
