4.1.2.3. Spectral Spreading
Spread mode PWM can be used to spread PWM common mode switching energy resulting in a peak energy
suppression greater than 20 dB at all frequencies. This Spectral Shaping feature is useful for mitigating EMI
radiation and eliminating inductors for filter-less applications. Spread Mode PWM can be programmed dynamically
by setting property PWM_CONFIG during normal operation without adversely affecting the internal audio
processing or the differential output signal integrity.
4.1.2.4. Spectral Shaping Noise-Free Notch for AM Radio (Si2705/07 only)
When using Spread Mode PWM with full rate PWM switching (960 kHz), a tunable noise-free notch can be
programmed via 2-Wire control to shape the switching noise and create a narrow frequency band in the AM radio
spectrum in which the PWM common mode switching energy is not allowed to spread. This noise-free notch is
