MAX7384

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-selector input, and a P power-on-reset (POR) supervisor. The clock output of MAX7384  can be switched at any time between the highspeed 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 highimpedance nodes makes the oscillator less susceptible to dirty or humid operating conditions. With a wide operating temperature range as standard, 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 for standard frequencies and contact the factory for custom frequencies. Refer to the MAX7378 data sheet for frequencies less than 10MHz.

The MAX7384 is available in an 8-pin MAX^® package. The MAX7384 standard operating temperature range is -40°C to +125°C. See the Applications Information section for extended operating temperature range.
