The PL671-30 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 CSEL[0:1] pins can switch between four pre-programmed configurations adding to the flexibility.
