MAX31091AUA/V+027

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31091AUA/V+027 is an automotive-grade clock generator operating within a -40°C to +125°C temperature range. It provides a factory-trimmed output frequency of 27MHz with a nominal accuracy of ±0.25% 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 pin-selectable center-dithered spread-spectrum capabilities with magnitudes of 0%, ±1%, ±2%, or ±4%. Packaged in an 8-pin µMAX format, it is AEC-Q100 qualified for automotive reliability.
