DS1090 Low-Frequency, Spread-Spectrum EconOscillator General Description Features The DS1090 is a low-cost, dithered oscillator intended Low-Cost, Spread-Spectrum EconOscillator to be used as an external clock for switched-mode Simple User Programming power supplies and other low-frequency applications. The Output Frequency Programmable from 125kHz to 8MHz dithering or sweeping function reduces peak-radiated Dither Percentage Programmable from 0% to 8% emissions from the power supply at its fundamental frequency, as well as harmonic frequencies. The device Dither Rate Programmable (f /512, 1024, 2048, MOSC consists of a resistor-programmed master oscillator, fac- or 4096) tory-programmed clock prescaler, and a pin-programmed 3.0V to 5.5V Single-Supply Operation dither circuit. These features allow the DS1090 to be used CMOS/TTL-Compatible Output in applications where a spread-spectrum clock is desired to reduce radiated emissions. A combination of factory-set Operating Temperature Range: -40C to +85C prescalers and external resistor allows for output frequencies ranging from 125kHz to 8MHz. Both dither frequency and Ordering Information dither percentage are set using control pins.
