The MAX7378 is a dual-speed silicon oscillator that replaces ceramic resonators, crystals, crystal-oscillator modules, and discrete reset circuits. It provides the primary and secondary clock source and reset function for microcontrollers in 3V, 3.3V, and 5V applications. The MAX7378 features a factory-programmed high-speed oscillator, a 32.768kHz oscillator, a clock selector input, and a microprocessor (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 MAX7378 is resistant to vibration and EMI. The high-output-drive current and absence of high-impedance nodes make the oscillator less susceptible to dirty or humid operating conditions. With a wide operating temperature range as standard, the MAX7378 is a good choice for demanding home appliance, industrial, and automotive environments. The MAX7378 is available in an 8-pin µMAX package. Refer to the MAX7384 data sheet for frequencies ≥10MHz. The MAX7378 standard operating temperature range is -40°C to +125°C. See the Applications Information section for the extended operating temperature range.
