Description
The MAX7384 dual-speed silicon oscillator replaces ceramic resonators, crystals, and crystal-oscillator modules as the primary and secondary clock source for microcontrollers in 3V, 3.3V, and 5V applications. The MAX7384 features a factory-programmed high-speed oscillator, a 32.768kHz oscillator, a clock enable input, a clock-selector input, and a µP power-on-reset (POR) supervisor. The clock output can be switched at any time between the high-speed clock and the 32.768kHz clock for low-power operation. Switchover is synchronized internally to provide glitch-free clock switching.

Unlike typical crystal and ceramic-resonator oscillator circuits, the MAX7384 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 as the MAX7384 is a good choice for demanding home appliance, industrial, and automotive environments.

The MAX7384 is available with factory-programmed frequencies ranging from 10MHz to 16MHz. See Table 1 in the full data sheet for standard frequencies and contact the factory for custom frequencies and POR thresholds.

The MAX7384 is available in an 8-pin µMAX® package. The MAX7384 operating temperature range is -40°C to +125°C.
