MAX31180AUA/V+T

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31180AUA/V+T 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 for automotive applications.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific part number suffix '/V+' confirms AEC-Q100 qualification status as indicated in the manufacturer's ordering information. Confirm the 'T' suffix corresponds to tape-and-reel packaging requirements for automated assembly processes. Ensure the component meets RoHS compliance specifications before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a low-jitter, programmable spread-spectrum clock source is required for EMI reduction in digital circuits. Ensure the input frequency falls within the 16MHz to 33.4MHz range. Verify that the system voltage aligns with the 3.0V to 3.6V operating window and that the 8-pin µSOP package fits the board layout constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the MAX31180 family of spread-spectrum crystal multipliers. The 'A' designation typically indicates an extended temperature range variant, while the '/V' suffix denotes automotive qualification. The '+T' suffix specifies lead-free/RoHS-compliant packaging in a tape-and-reel format for surface-mount technology.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX31180AUA+ and MAX31180AUA+T. These variants share identical electrical characteristics but may lack the specific automotive qualification associated with the '/V' suffix.
