Product Overview
The DS1090U-32+ is a low-frequency, spread-spectrum EconOscillator in 8 pin µMAX package. It 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 four basic circuit blocks such as resistor-programmed master oscillator, factory-programmed clock prescaler, a pin-programmed dither circuit and the voltage-bias circuit that provides the feedback path to the master oscillator for frequency control and dithering functions. 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 250KHz. Both dither frequency and dither percentage are set using control pins.
- Supply voltage range is 3V to 5.5V
- Operating temperature range from -40°C to 85°C
- Simple user programming
- Dither percentage programmable from 0% to 8%
- Dither rate programmable (fMOSC/512, 1024, 2048 or 4096)
- CMOS/TTL compatible output
- Prescaler divides the frequency of master oscillator by 32
Applications
Signal Processing, Power Management, Industrial, Portable Devices
