MAX31091AUA/V+033

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31091AUA/V+033 is an automotive-grade spread-spectrum clock generator operating within a 3.0V to 3.6V supply range. Factory trimmed for a center frequency of 33.3MHz, it supports frequencies from 200kHz to 66.6MHz with ±0.25% accuracy at +25°C and ±1.75% across the -40°C to +125°C temperature range. The device features pin-selectable dither magnitudes (0%, ±1%, ±2%, ±4%) and selectable dither rates to reduce EMI. It utilizes an 8-pin µMAX package and holds AEC-Q100 qualification.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and exact factory-programmed frequency. Confirm that the component meets current RoHS compliance standards as indicated by the '+' designation in the part number.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency clock source with spread-spectrum capabilities is required for automotive applications. Ensure the design accommodates the 3.0V to 3.6V supply voltage and the 8-pin µMAX footprint. Verify that the default 33.3MHz frequency aligns with system requirements without needing external dividers.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MAX31091 EconOscillator family, which provides low-cost, factory-trimmed clock generators. The '033' suffix specifically denotes the 33.3MHz output frequency option. The '/V' indicates automotive qualification, while the absence of a 'T' prefix suggests tube packaging rather than tape-and-reel.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other variants within the MAX31091 series with different frequency suffixes (e.g., MAX31091AUA/V+066 for 66.6MHz). Cross-family replacements require verification of pin compatibility and electrical specifications.
