SM8760CA Spread Spectrum Clock Generator OVERVIEW The SM8760CA is a compact clock generator IC with 4-times multiplication clock signal output that has a spread spectrum (SS) function to reduce undesirable EMI radiation. The SM8760CA has built-in crystal oscillator circuit, PLL, and loop lter. It accepts an input clock signal, generated using an external crystal or direct external clock input, and outputs 1 SS-modulated 4-times multiplication clock signal and 1 unmodulated reference signal. In addition, the SM8760CA features control pins to select SS modulation function ON/OFF and power-down modes.
