MAX31180AUA+T

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31180AUA+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 consumes 15mA at 16MHz. The device features selectable clock multiplier rates of 1x, 2x, or 4x, and supports center dithering magnitudes of ±0.5%, ±1.0%, or ±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 automotive qualification, while the standard version lacks this certification. Confirm the '+T' suffix corresponds to tape-and-reel packaging requirements for automated assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the MAX31180AUA+T when automotive reliability is mandatory. Ensure the application requires a single-ended output compatible with the SSO pin. Verify that the input frequency falls within the 16MHz to 33.4MHz range and that the desired output frequency does not exceed 134MHz after multiplication.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the MAX31180 family of spread-spectrum crystal multipliers. The MAX31180AUA+T specifically denotes the automotive-grade variant packaged in an 8-pin µSOP format. It shares functional characteristics with the non-automotive MAX31180 but adheres to stricter automotive quality standards.
