The MAX7381 is a silicon oscillator intended as a low-cost
improvement to ceramic resonators, crystals, and crystal
oscillator modules as the clock source for microcontrollers
and UARTs in 3V, 3.3V, and 5V applications.
The MAX7381 is an integrated oscillator, supplied at specific
frequencies, just like crystals and resonators, and
with a rail-to-rail, 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 required for setting or adjusting the frequency.
Unlike typical crystal and ceramic resonator oscillator circuits,
the MAX7381 is resistant to vibration and EMI. The
high output-drive current and absence of high-impedance
nodes make the oscillator invulnerable to dirty or
humid operating conditions. With a wide operating temperature
range as standard, the oscillator is a good
choice for demanding appliance and automotive environments.
The MAX7381 is available with frequencies in the
10MHz to 16MHz range.
The MAX7381 is offered in a space-saving 3-pin SC70
package. All ICs are guaranteed to operate over the
-55°C to +135°C temperature range and specified from
the -40°C to +125°C temperature range.
