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.
