The PL671-25 is a high performance programmable spread spectrum clock. It allows for programming the
modulation type (Center or Down Spread), 16 modulation magnitudes (В±0.125% to В±2.0% or -0.25% to -4.0%) and
multiplication factor. The SSOnOff pin can be used to enable and disable the spread on the output for easy
system performance comparison during EMI testing.
