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).

ABSOLUTE MAXIMUM RATINGS
Voltage on VCC Relative to Ground.......................-0.5V to +6.0V
Voltage on DR, SEL0, SEL1 Relative
to Ground* ..............................................-0.5V to (VCC + 0.5V)
*This voltage must not exceed 6.0V.

Soldering Temperature...................See J-STD-020 Specification
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
