MAX31091AUA/V+200

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31091AUA/V+200 is an automotive-grade clock generator operating within a -40°C to +125°C temperature range. It provides a factory-trimmed output frequency of 0.2MHz with ±0.25% nominal accuracy at 25°C and ±1.75% across the full temperature and voltage range. The device operates on a 3.0V to 3.6V supply, drawing a typical active current of 16mA. It features center-dithered spread-spectrum capability with pin-selectable magnitudes of 0%, ±1%, ±2%, or ±4%. Packaged in an 8-pin µMAX format, it is AEC-Q100 qualified for automotive reliability.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '200' confirms the 0.2MHz factory trim frequency. Confirm that the '/V' designation indicates AEC-Q100 automotive qualification and the '+' denotes lead-free/RoHS compliance. Ensure the package code U8+4 matches the required 8-pin µMAX footprint for PCB layout.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a low-cost, fixed-frequency automotive clock source is required. The 0.2MHz frequency is suitable for lower-speed interfaces or as a reference oscillator. Consider the power consumption of approximately 16mA and ensure the load capacitance requirements (typically 15pF) are met by the circuit design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MAX31091 EconOscillator family, which offers various factory-programmed frequencies ranging from 200kHz to 66.6MHz. The 'AUA/V' variant specifically denotes the automotive-qualified version in the 8-pin µMAX package. Other suffixes like 'T' indicate tape-and-reel packaging options for the same electrical specifications.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same family include other MAX31091AUA/V variants with different factory-trimmed frequencies (e.g., MAX31091AUA/V+033 for 33.3MHz). Verify that the target application can accommodate the specific output frequency difference if substituting with another model from the series.
