Maxim Integrated Products introduces the MAX7387-MAX7391 family of silicon oscillators, offering all the supervisory functions of medium-accuracy silicon oscillators in a single, surface-mount microMAX® package. These devices switch frequencies and range from 32 kHz for low-power modes, to 16 MHz in high-speed mode. The MAX7387-MAX7391 are suitable for high-reliability systems, as they do not utilize external high-impedance nodes commonly found in ceramic resonator circuits. This makes them less susceptible to dirt, humidity and high-EMI/ESD conditions. Also, because the oscillators do not rely on mechanical methods, they are less sensitive to environmental concerns such as vibration and shock. Integrated into this oscillator family is a reset output to interface with a microcontroller, power-fail detection to alert the system of an impending power failure and a watchdog to monitor the health of the system. At a supply voltage of 3.3 V, the supply current is 2.9 mA for the 16 MHz device.
