MAX31180AUA+

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31180AUA+ is a low-jitter, crystal-based clock generator with an integrated phase-locked loop (PLL) designed to generate spread-spectrum clock outputs ranging from 16MHz to 134MHz. It operates on a single 3.0V to 3.6V supply and supports selectable clock multiplier rates of 1x, 2x, and 4x. The device features center spread-spectrum dithering with magnitudes of ±0.5%, ±1.0%, and ±1.5%. It includes a power-down mode for high-impedance output and is qualified under AEC-Q100 standards.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific part number suffix matches the required qualification level. The 'A' designation indicates the temperature range, while the '/V' suffix denotes AEC-Q100 automotive qualification. Confirm package type and RoHS compliance status before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low cycle-to-cycle jitter and spread-spectrum capabilities are required for EMI reduction. Ensure the input frequency falls within the 16MHz to 33.4MHz range. Verify that the application requires the -40°C to +125°C operating temperature range and single-supply operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the MAX31180 family of spread-spectrum crystal multipliers. The MAX31180AUA+ variant specifically provides the standard commercial/industrial temperature range (-40°C to +125°C) in an 8-pin µSOP package without the automotive qualification suffix.
