4.12.2 DSM with Slew Rate Control
Data Signal Modulator with Slew Rate Control
4.12.2.1 Introduction
The Data Signal Modulator (DSM) is a peripheral that allows the user to mix a data stream, also known as a modulator signal, with a carrier signal to produce a modulated output. Both the carrier and the modulator signals are supplied to the DSM module either internally, from the output of a peripheral, or externally through an input pin. The modulated output signal is generated by performing a logical “AND” operation of both the carrier and modulator signals, and then provided to the DSM_out pin. This variant of the module has a Slew Rate Control.
