The DS1086 EconOscillator is a programmable clock generator that produces a spread-spectrum (dithered) square-wave output of frequencies from 260kHz to 133MHz. The selectable dithered output reduces radi- ated-emission peaks by dithering the frequency 2% or 4% below the programmed frequency. The DS1086 has a power-down mode and an output-enable control for power-sensitive applications. All the device settings are stored in nonvolatile (NV) EEPROM memory allowing it to operate in stand-alone applications.
The DS1086 EconOscillator™ is a programmable clock generator that produces a spread‑spectrum (dithered) square‑wave output from 260 kHz to 133 MHz. Settings are stored in non‑volatile EEPROM, allowing stand‑alone operation and power‑down mode for low‑power applications.
Key features include selectable 2% or 4% dither to reduce EMI, glitch‑less output‑enable control, a 2‑wire serial interface for programming, and operation over a 0 °C‑70 °C temperature range. The device is supplied in 8‑lead µSOP/SOT packages (DS1086U, DS1086U+, DS1086Z, DS1086Z+).
