DS1094L - Multiphase Spread-Spectrum EconOscillator

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.

Key Features

  • EconOscillator™ with Two, Three, or Four Phase Outputs.
  • Ideally Suited as the Clock Generator for SwitchMode Power Supplies.
  • Output Frequencies Programmable from 2MHz to 31.25kHz.
  • Dithered Output Significantly Reduces EMI Emissions.
  • No External Timing Components Required.
  • Nonvolatile (NV) Configuration Settings.
  • User-Programmable.
  • Factory Programmed Options Available.
  • Operating Temperature Range: -40°C to +85.

lator 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. The outputs generated by the DS1094L are used by DC-DC circuitry to efficiently sh
