PLL spread spectrum clock generation (SSCG) characteristics
The spread spectrum clock generation (SSCG) feature allows to reduce electromagnetic
interferences (see
SSCG parameters constraint
Equation 1
The frequency modulation period (MODEPER) is given by the equation below:
Equation 2
Equation 2 allows to calculate the increment step (INCSTEP):
An amplitude quantization error may be generated because the linear modulation profile is
obtained by taking the quantized values (rounded to the nearest integer) of MODPER and
INCSTEP. As a result, the achieved modulation depth is quantized. The percentage
quantized modulation depth is given by the following formula:
