MAX7382

19-3491; Rev 0; 1/05 Silicon Oscillator with Reset Output General Description The MAX7382 silicon oscillator replaces ceramic resonators, crystals, and crystal-oscillator modules as the clock source for microcontrollers in 3V, 3.3V, and 5V applications. The MAX7382 features a factory-programmed oscillator and a microprocessor (µP) poweron-reset (POR) supervisor. Unlike typical crystal and ceramic-resonator oscillator circuits, the MAX7382 is resistant to vibration and EMI. The high-output-drive current and absence of highimpedance nodes makes the oscillator less susceptible to dirty or humid operating conditions. With a wide operating temperature range as standard, the MAX7382 is a good choice for demanding home appliance and automotive environments. The MAX7382 is available with factory-programmed frequencies ranging from 10MHz to 32MHz. See Table 2 for standard frequencies and contact the factory for custom frequencies. Refer to the MAX7376 data sheet for frequencies less than 10MHz. The MAX7382 is available in a 5-pin SOT23 package. The MAX7382 standard operating temperature range is -40°C to +125°C. See the Applications Information section for extended operating temperature range. ♦ 2.7V to 5.5V Operation ♦ 10MHz to 32MHz Oscillator ♦ Integrated POR ♦ ±10mA Clock Output Drive Capability ♦ 2.5% Initial Accuracy ♦ ±50ppm/°C Frequency Drift ♦ 50% Duty Cycle ♦ 5ns Output Rise and Fall Time ♦ Low Jitter: 80psP-P at 16MHz ♦ 4mA Operating Current at 16MHz ♦ -40°C to +125°C Temp...
