MAX31091AUA/V+330

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31091AUA/V+330 is an automotive-grade, low-cost clock generator housed in an 8-pin µMAX package. It operates on a 3.0V to 3.6V supply and functions within the -40°C to +125°C temperature range. Factory trimmed for a nominal output frequency of 33.0MHz with ±0.25% accuracy at 25°C, it supports center-spread-spectrum outputs via pin-selectable dither magnitudes (0%, ±1%, ±2%, ±4%) and rates. The device draws a typical active supply current of 16mA and provides a square-wave output suitable for reducing radiated emissions.
