MAX31180AUA/V+

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31180AUA/V+ 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 consumes 15mA during normal operation at 16MHz. The device features selectable clock multiplier rates of 1x, 2x, or 4x, and center spread-spectrum dithering magnitudes of ±0.5%, ±1.0%, or ±1.5%. It includes a power-down mode with 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 both AEC-Q100 qualification and lead-free/RoHS compliance. Ensure the ordering suffix matches the required packaging format, as 'T' indicates tape and reel while absence implies standard packaging. Confirm the component meets the specified -40°C to +125°C temperature range requirements for the target application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a low-jitter, crystal-based clock multiplier with spread-spectrum capabilities is required. Ensure the input crystal frequency falls between 16MHz and 33.4MHz and has an ESR below 90Ω. Verify that the system requires a single 3.0V to 3.6V supply voltage and fits within the 8-pin µSOP package constraints. Consider the power-down functionality if standby current reduction is necessary.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the MAX31180 family of spread-spectrum crystal multipliers manufactured by Maxim Integrated. The MAX31180AUA/V+ variant specifically denotes the automotive-qualified version housed in an 8-pin µSOP package. It serves as a specialized clock generation solution for reducing electromagnetic interference (EMI) in digital communication and computing systems through controlled frequency dithering.

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 and pin configurations but lack the specific AEC-Q100 automotive qualification associated with the '/V' suffix.
