MAX31091AUA/V+T033

P1-P3P4-P6P7-P8
General 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 auto-
motive temperature range (-40°C to +125°C).
Applications
● Automotive Infotainment
● Navigation
● Advanced Driver Assistance System (ADAS)
● Engine Control Unit (ECU) Instrumentation
Features
● Spread-Spectrum Clock Output from 200kHz to
66.6MHz
● -40°C to +125°C Operating Temperature Range
● ±1.75% Accuracy Across Temperature
● Factory Trimmed
● Center-Dithered Spread-Spectrum Output
● Pin-Selectable Center-Dither Magnitude of 0%, ±1%,
±2%, or ±4%
● Pin-Selectable Dither Rate
● 3.0V to 3.6V Supply Operation
● Lead(Pb)-Free, 8-Pin µMAX Package

Absolute Maximum Ratings
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
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.
