This application note presents an easy-to-use frequency calculator, for determining the register values to be programmed into the DS1094L Multiphase Spread-Spectrum EconOscillator. The DS1094L is capable of generating 4 multiphase, spread-spectrum, square wave outputs between 31.25kHz and 2MHz, in either 2, 3 or 4 phase modes. The spread-spectrum system function is important when EMI is a concern of the end application, such as switched-mode power supplies. ……
