MAX7377AXRD+T by Analog Devices

Silicon Oscillator with Low-Power Frequency Switching


The MAX7377 dual-speed silicon oscillator with reset is a replacement for ceramic resonators, crystals, crystal oscillator modules, and discrete reset circuits. The device provides the primary and secondary clock source for microcontrollers in 3V, 3.3V, and 5V applications. The MAX7377 features a factory-programmed high-speed oscillator, a 32.768kHz oscillator, 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 MAX7377 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 MAX7377 is a good choice for demanding home appliance and industrial environments. The MAX7377 is available in factory-programmed frequencies from 32.768kHz to 10MHz. See Table 1 in the full data sheet for standard frequencies and contact the factory for custom frequencies. The MAX7377 is available in a 5-pin SOT23 package. Refer to the MAX7383 data sheet for frequencies ≥10MHz. The MAX7377 standard operating temperature range is -40°C to +125°C. See the Applications Information section of the full data sheet for the extended operating temperature range.
