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).

Applications

Automotive Infotainment

POS Terminals

LCD Displays

Printers
