Description

The MAX31091 is a low-cost clock generator that is factory trimmed to output frequencies from 200kHz to 66.6MHz with a nominal accuracy of ±0.25%. The device can also produce a center-spread-spectrum output with pin-selectable dither magnitude and rate. Assembled in an 8-pin µMAX® package, the MAX31091 is designed to operate with a 3.0V to 3.6V power supply over the automotive temperature range (-40°C to +125°C).
