Spread-Spectrum Oscillator IC Emits 20 dB Less EMI Than Crystals

The DS1087L single-chip, 3-V spread-spectrum oscillator produces a dithered square-wave fixed output of 260 kHz to 133 MHz without any user programming. With either a 2% or 4% dithered output, the DS1087L reduces electromagnetic interference (EMI) up to 20 dB relative to crystal oscillators. The chip comes in an eight-pin microSOP. Pricing starts at $0.75 each per 1000.
