Description

The MAX7376 silicon oscillator with reset, is a replacement for ceramic resonators, crystals, crystal oscillator modules, and discrete reset circuits. The MAX7376 provides the primary clock source and reset function for microcontrollers in 3V, 3.3V, and 5V applications. The MAX7376 features a factory-programmed high-speed oscillator and a microprocessor (P) power-on-reset (POR) supervisor.

Unlike typical crystal and ceramic resonator oscillator circuits, the MAX7376 is resistant to vibration and EMI. The high-output-drive current and absence of highimpedance nodes make the oscillator less susceptible to dirty or humid operating conditions. With a wide operating temperature range as standard, the MAX7376 is a good choice for demanding home appliance, industrial, and automotive environments.

The MAX7376 is available in factory-programmed frequencies from 32.768kHz to 10MHz. See Table 2 for standard frequencies and contact the factory for custom frequencies.

The MAX7376 is available in a 5-pin SOT23 package. Refer to the MAX7382 data sheet for frequencies 10MHz. The MAX7376 standard operating temperature range is -40°C to +125°C. See the Applications Information section for the extended operating temperature range.
