MAX7382 Datasheet, PDF (1/8 Pages) Maxim Integrated Products – Silicon Oscillator with Reset Output

Silicon Oscillator with Reset Output
General Description
The MAX7382 silicon oscillator replaces ceramic res-
onators, crystals, and crystal-oscillator modules as the
clock source for microcontrollers in 3V, 3.3V, and 5V
applications. The MAX7382 features a factory-pro-
grammed oscillator and a microprocessor (µP) power-
on-reset (POR) supervisor.
Unlike typical crystal and ceramic-resonator oscillator
circuits, the MAX7382 is resistant to vibration and EMI.
The high-output-drive current and absence of high-
impedance nodes makes the oscillator less susceptible
to dirty or humid operating conditions. With a wide
operating temperature range as standard, the
MAX7382 is a good choice for demanding home appli-
ance and automotive environments.
The MAX7382 is available with factory-programmed fre-
quencies ranging from 10MHz to 32MHz. See Table 2
for standard frequencies and contact the factory for
custom frequencies. Refer to the MAX7376 data sheet
for frequencies less than 10MHz.
The MAX7382 is available in a 5-pin SOT23 package.
The MAX7382 standard operating temperature range is
-40°C to +125°C. See the Applications Information sec-
tion for extended operating temperature range.
