Analog Devices / Maxim Integrated DS1091L Spread-Spectrum EconOscillator™

Analog Devices Inc. DS1091L Spread-Spectrum EconOscillator™ is a 3V all-silicon center spread clock generator to reduce EMI in the automotive temperature range. This ADI device is factory-trimmed to output frequencies from 130kHz to 66.6MHz with a nominal accuracy of ±0.25%. ADI DS1091L EconOscillator can also produce a center- or down-dithered spread-spectrum output with pin-selectable dither magnitude and rate. The DS1091L is designed to operate with a 3V to 3.6V power supply over a temperature range of -40°C to +125°C. This ADI device is ideal for use in automotive infotainment and industrial control applications.
