DS1091L：Automotive Temperature Range Spread-Spectrum EconOscillator™

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

The DS1091L is a low-cost clock generator that is factory-trimmed to output frequencies from 130kHz to 66.6MHz with a nominal accuracy of ±0.25%. The device can also produce a center- or down-dithered spread-spectrum output with pin-selectable dither magnitude and rate. Assembled in an 8-pin µMAX® package, the DS1091L is designed to operate with a 3.0V to 3.6V power supply over the automotive temperature range (-40°C to +125°C).
