DS1090 Datasheet | Maxim Integrated

Low-Frequency, Spread-Spectrum EconOscillator General Description The DS1090 is a low-cost, dithered oscillator intended to be used as an external clock for switched-mode power supplies and other low-frequency applications. The dithering or sweeping function reduces peak-radiated emissions from the power supply at its fundamental frequency, as well as harmonic frequencies. The device 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 bination of factory-set prescalers and...
