Automotive Temperature Range
Spread-Spectrum EconOscillator™
General Description
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).
