DALLAS Semiconductor has released the DS1094L EconOscillator, the world's only single component, multi-phase, spread spectrum clock oscillator. It is available from Arrow Electronics .

It offers output frequencies between 31.25kHz and 2MHz, with operation over the industrial temperature range from -40°C to +85°C.

It generates four multi-phase, spread spectrum, square wave outputs. 0%, 2%, 4%, or 8% dither of the internal master oscillator can reduce peak spectral energy at the fundamental and harmonic-clock frequencies. This significantly reduces system level electromagnetic interference (EMI). The DS1094L is suited to functioning as a clock generator for switched-mode power supplies.

It is available in 8-pin microSOP, and operates in the 3.0V to 3.6V range.
