Industry's Only 3V, All-Silicon, Center-Spread Clock Oscillator to Reduce EMI in the Automotive Temperature Range

SUNNYVALE, CA —Maxim Integrated Products introduces the DS1091L, an integrated spread-spectrum, silicon EconOscillator™ that reduces EMI emissions in harsh automotive environments of -40°C to +125°C. The DS1091L is factory-trimmed to be used as a stand-alone oscillator from 130kHz to 66.6MHz. The center frequency is accurate to within ±1.75% over voltage and temperature.

The DS1091L reduces radiated emissions (RMS voltage) up to 23dB compared to crystal oscillators. Used as the system clock, the spread-spectrum DS1091L can simplify, or even eliminate shielding and filtering, which reduces cost and minimizes design time. To allow simple optimization of system design, the DS1091L dither magnitude (center- or down-dither options) and dither frequency are pin-selectable. Spread-spectrum modulation can also be disabled.

The DS1091L operates from 3.0V to 3.6V and is available in the tiny 8-pin µMAX® (and a 3mm x 3mm TDFN package under development). Pricing begins at $0.72 (1000-up, FOB USA.)
