Clock Source
The device supports fixed-frequency modulation with an internal or external clock. The modulation mode is selected through CTRL1.CM[1:0] (operating mode select bits).
Master Configuration
In master mode, 10 modulation frequencies are available in fixed-frequency modulation mode. Program CTRL0.MDIV[3:0] (master clock-divide ratio bits) for the desired frequency.
Slave Configuration
Configuring the device as a slave allows an external clock source to provide the switching frequency. In this case, apply the external clock signal at SYNC at double the desired switching frequency.
