The DS1086 spread spectrum EconOscillator, a low-EMI, all-silicon clock oscillator. User-programmable for 0%, 2%, or 4% spread settings, this integrated circuit offers up to 20 dB reduction in radiated emissions (RMS voltage) relative to crystal oscillators. The DS1086 clock synthesizer can be used as a standalone oscillator to generate clock output from 360 kHz to 133 MHz. A 2-wire serial interface allows in-circuit, on-the-fly programming of all control registers. The 5 V DS1086 is available in an 8-pin SO package.
