Description

The MAX7383 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 MAX7383 features a factory-programmed high-speed oscillator, a 32.768kHz oscillator, a clock enable input, and a clock-selector input. 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 MAX7383 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 MAX7383 is a good choice for demanding home appliance and automotive environments. The MAX7383 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 UVLO thresholds. The MAX7383 is available in a 5-pin SOT23 package. The MAX7383 operating temperature range is -40°C to +125°C.
