MAX31091AUA/V+T330

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31091AUA/V+T330 is an automotive-grade clock generator housed in an 8-pin µMAX package. It outputs a factory-trimmed 33.0MHz center-spread-spectrum signal with ±0.25% nominal accuracy at +25°C. The device operates on a 3.0V to 3.6V supply and supports dither magnitudes of 0%, ±1%, ±2%, or ±4% via pin selection. It functions within the -40°C to +125°C temperature range, consumes 16mA typical supply current, and meets AEC-Q100 qualification standards.
