The PL671-29 is a high performance programmable spread spectrum clock. It allows for programming the
modulation type (Center or Down Spread) and 16 modulation magnitudes (В±0.125% to В±2.0% or -0.25% to -4.0%).
The SSOnOff pin can be used to enable and disable the spread on the output for eas y system performance
comparison during EMI testing.
