Compare 152 Modulation/Demodulation IP from 36 vendors (1 - 10)

APB Pulse Width Modulator
- The APB PWM Module is a standard APB peripheral that generates a programmable duty cycle output signal.
- The frequency of the output waveform is either PCLK/256 or PCLK/4096, depending on whether a 4-bit prescaler is enabled.
Pulse Width Modulator
- The PWM IP core implements a compact and highly flexible Pulse Width Modulator. The core generates a repeated pattern of pulse trains of run-time configurable period and duty cycle.
- Those pulse trains can be used in a wide variety of applications including but not limited to motor control and LED dimming. They can also be filtered with a lowpass filter to implement Digital to Analog Converters (DAC).
