Maxim DS1090 Spread-Spectrum EconOscillator

Maxim Integrated DS1090
Spread-Spectrum EconOscillator

Maxim Integrated DS1090 low-frequency, spread-spectrum EconOscillator™ is the industry's first spread-spectrum resistor-programmable oscillator. This Maxim Integrated device is a dithered oscillator intended for use as an external clock for switched-mode power supplies and other low-frequency applications. The dithering or sweeping function of the Maxim Integrated DS1090 reduces peak-radiated emissions from the power supply at its fundamental frequency, as well as harmonic frequencies. This Maxim Integrated EconOscillator consists of a resistor-programmed master oscillator, factory-programmed clock prescaler, and a pin-programmed dither circuit. These features allow the DS1090 to be used in applications where a spread-spectrum clock is desired to reduce radiated emissions. A combination of factory-set prescalers and external resistor allows for output frequencies ranging from 125kHz to 8MHz. Both dither frequency and dither percentage are set using control pins.
