MAXIM INTEGRATED / ANALOG DEVICES DS1090U16 Spread-Spectrum Oscillator
The DS1090U-16+ is a low-frequency, spread-spectrum oscillator in an 8-pin µMAX package. It functions as an inexpensive, dithered clock source designed for external use in switching power supplies and other low-frequency applications. Its dithering or sweeping capability helps reduce radiated emissions from the power supply by spreading the electromagnetic spectrum at the fundamental and harmonic frequencies. The device includes a resistor-programmed master oscillator, a factory-set clock prescaler, a pin-configurable dither circuit, and a voltage-bias circuit that provides feedback for frequency control and dithering. It offers output frequencies between 250 kHz and 500 kHz, with programmable dither percentage (up to 8%) and dither rate (fMOSC divided by 512, 1024, 2048, or 4096). The supply voltage ranges from 3V to 5.5V, and it operates from -40°C to 85°C. The output is CMOS/TTL compatible. It is suitable for applications in signal processing, power management, industrial controls, portable devices, embedded microcontrollers, printers, servers, and switch-mode power supplies.
