OVERVIEW
The SM8761 series are compact clock generator ICs that have a spread spectrum (SS) function to reduce undesirable EMI radiation. They have a built-in crystal oscillator circuit, PLL, and loop filter. They accept an input clock signal, generated using an external crystal or direct external clock input, and output an SS-modulated clock signal. In addition, versions are available for center spread and down spread modulation mode, and all have a mode control pin to select the SS modulation function.
