Description
I External reference frequency input. Connect to externally generated reference signal.
I Digital logic input used to select modulation rate. This pin has an internal pull-up resistor.
I Digital logic input used to select Spreading Range. This pin has an internal pull-up resistor.
P Ground to entire chip. Connect to system ground.
I
Digital logic input used to enable Spread Spectrum function (Active LOW). Spread Spectrum
function enabled when LOW, disabled when HIGH. This pin has an internal pull-low resistor.
O Spread spectrum clock output.
I Digital logic input used to select Spreading Range. This pin has an internal pull-up resistor.
P Power supply for the entire chip (3.3V)
