DS1081L Spread-Spectrum Clock Modulator

The DS1081L is a spread-spectrum clock modulator IC that reduces EMI in high clock-frequency-based, digital electronic equipment. Using an integrated phase-locked loop (PLL), the DS1081L accepts an input clock signal in the range of 20MHz to 134MHz and delivers a spread-spectrum modulated output clo.

DS1081L Features
