Rainbow Electronics DS1091L - Manual

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
