MAX7375

19-3060; Rev 2; 7/04 3-Pin Silicon Oscillator General Description The MAX7375 is a silicon oscillator, intended as a lowcost improvement replacing ceramic resonators, crystals, and crystal oscillator modules used as the clock source for microcontrollers and UARTs in 3V, 3.3V, and 5V applications. The MAX7375 is a fully integrated oscillator, supplied at specific factory-trimmed frequencies with a Rail-toRail® 50% duty cycle square-wave output. The oscillator frequency is generated directly without the use of a phase-locked loop (PLL). No additional components are used to set or adjust the frequency. Unlike typical crystal and ceramic resonator oscillator circuits, the MAX7375 is highly resistant to vibration and EMI. The high output drive current and absence of high-impedance nodes also makes the oscillator less susceptible to dirty or humid operating conditions. With a wide operating temperature range, the oscillator is a good choice for demanding home appliance and automotive environments. Available in 3-pin space-saving SC70 and SOT23 packages, the MAX7375 is offered in standard and nonstandard factory-set frequencies ranging from 600kHz to 9.99MHz. See the MAX7381 data sheet for frequencies ≥10MHz. The MAX7375’s standard operating temperature range is -40°C to +125°C. See the Applications Information section for extended operating temperature range. ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ Features 2.7V to 5.5V Operation Factory-Trimmed Oscillator (600kHz to 9.99MHz) No External Components ...
