DATASHEET

6.2.2. Data and Data Clock Usage

In MCU mode the data to be transmitted is applied exclusively via the DATA input. The DATA input is sampled at the crystal

frequency, fxosc. Where the MCU mediates the data rate and no gaussian or bit filtering is required, then the use of the data

clock signal is optional. However, where filtering is to be used or the specified data rate accuracy is to be achieved, then

the rising edge of the data clock, DCLK, signal must be used to clock the data into the SX1230 DATA input.
