General Description

The DS1094L is a silicon oscillator that generates four multiphase, spread-spectrum, square-wave outputs. Frequencies between 2MHz and 31.25kHz can be output in either two, three, or four-phase mode. The internal master oscillator can be dithered by either 0, 2, 4, or 8 to reduce the amount of peak spectral energy at the fundamental and harmonic clock frequencies. This significantly reduces the amount of electromagnetic interference (EMI) radiation that is generated at the system level. The DS1094L is ideally suited as a clock generator for switched-mode power supplies.
