MAX31091AUA/V+T033

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31091AUA/V+T033 is an automotive-grade clock generator housed in an 8-pin µMAX package. It operates on a 3.0V to 3.6V supply and functions within a temperature range of -40°C to +125°C. The device outputs a center-spread-spectrum square wave at a factory-trimmed frequency of 33.3MHz with ±0.25% nominal accuracy. Key electrical parameters include a typical supply current of 16mA, output rise/fall times around 1ns, and jitter of 0.3% RMS at 50MHz. It supports pin-selectable dither magnitudes and rates for EMI reduction.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'T033' corresponds to the tape-and-reel packaging format and the 33.3MHz factory trim frequency as listed in the manufacturer's ordering information table. Confirm that the component meets RoHS compliance requirements indicated by the '+' designation in the part number.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency, low-cost clock source with spread-spectrum modulation is required for automotive applications. Ensure the design accommodates the 16mA typical supply current and utilizes the SEL0/SEL1 pins to configure the desired dither magnitude if emission reduction is necessary.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MAX31091 EconOscillator family, which provides various factory-programmed frequencies ranging from 200kHz to 66.6MHz. The 'AUA/V' prefix indicates automotive qualification and the µMAX package, while the '+T033' suffix specifies the reel packaging and the specific 33.3MHz output frequency.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include MAX31091AUA/V+033 (tube packaging) or other frequency variants like MAX31091AUA/V+066. Verify that any substitute maintains the 8-pin µMAX footprint and AEC-Q100 automotive qualification status.
