Silicon Oscillator with Reset Output and Enable

The MAX7382 silicon oscillator replaces ceramic resonators, crystals, and crystal-oscillator modules as the clock source for microcontrollers in 3V, 3.3V, and 5V applications. The MAX7382 features a factory-programmed oscillator, a microprocessor (µP) power-on-reset (POR) supervisor, and a clock enable input.

Unlike typical crystal and ceramic-resonator oscillator circuits, the MAX7382 is resistant to vibration and EMI. The high-output-drive current and absence of high-impedance nodes makes the oscillator less susceptible to dirty or humid operating conditions. With a wide operating temperature range, the MAX7382 is a good choice for demanding home appliance and automotive environments.

The MAX7382 is available with factory-programmed frequencies ranging from 10MHz to 16MHz. See the full data sheet for standard frequencies and contact the factory for custom frequencies and POR thresholds.

The MAX7382 is available in a 5-pin SOT23 package. The MAX7382 operating temperature range is -40°C to +125°C.
