DS1091L - Automotive Temperature Range Spread Spectrum Econoscillator

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.
