SX1230
Integrated Transmitter IC
ADVANCED COMMUNICATIONS & SENSING
DATASHEET
The SX1230 also includes two timing references; an RC oscillator, for sleep mode operation of the SPI interface (in MCU
mode), and a 32 MHz crystal oscillator, which serves as the low-noise frequency reference of the PLL. The references and
supply voltages are provided by the power distribution system which includes several regulators allowing true battery
powered operation.
