Dallas Semiconductor claims its DS1087L spread-spectrum EconOscillator is the world's only 3 V single-chip oscillator. This fixed-frequency device requires no programming, and with either a 2% or 4% dithered output, the device reduces EMI up to 20 dB relative to crystal oscillators. The DS1087L EconOscillator is a clock generator that produces a spread-spectrum (dithered) square-wave fixed output of 260kHz to 133 MHz. The manufacturer says this one chip can replace crystal or crystal/oscillator and reduces radiated-emission peaks by dithering the output frequency 2% or 4% below the operating frequency. The chip has a power-down mode and an output-enable control for power-sensitive applications. The DS1087L is currently available in a 3 V version and comes in an 8-pin microSOP.
