Rainbow Electronics MAX7375 - Manual

General Description
The MAX7375 is a silicon oscillator, intended as a low-
cost improvement to replace ceramic resonators, crys-
tals, 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-to-
Rail® 50% duty cycle square-wave output. The oscilla-
tor frequency is generated directly without the use of a
phase-locked loop (PLL). No additional components
are used for setting or adjusting the frequency.
Unlike typical crystal and ceramic resonator oscillator
circuits, the MAX7375 is resistant to vibration and EMI.
The high output drive current and absence of high-
impedance nodes make 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.
The MAX7375 is offered in space-saving 3-pin SC70
and SOT23 packages. All parts are guaranteed to oper-
ate over the -55°C to +135°C temperature range and
are specified from -40°C to +125°C.
