General Description
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 microcon-
trollers and UARTs in 3V, 3.3V, and 5V applications.
The MAX7381 is an integrated oscillator, supplied at spe-
cific 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 compo-
nents are required for setting or adjusting the frequency.
Unlike typical crystal and ceramic resonator oscillator cir-
cuits, the MAX7381 is resistant to vibration and EMI. The
high output-drive current and absence of high-imped-
ance nodes make the oscillator invulnerable to dirty or
humid operating conditions. With a wide operating tem-
perature range as standard, the oscillator is a good
choice for demanding appliance and automotive environ-
ments. 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.

Typical Operating Circuit
Selector Guide appears at end of data sheet.
The MAX7381 is available in factory-set frequencies from
10MHz to 16MHz. There are four standard versions 10MHz,
12MHz, 14MHz, and 16MHz, shown in the Selector Guide) with
a required order increment of 2.5K. Nonstandard frequencies
are also available with a required order increment of 10K. For
nonstandard versions, contact factory for availability and
ordering information. All versions are available in tape and reel
only.
Refer to the MAX7375 data sheet for output frequencies below
10MHz.
