The MAX7383 dual-speed silicon oscillator replaces
ceramic resonators, crystals, and crystal-oscillator
modules as the primary and secondary clock source for
microcontrollers in 3V, 3.3V, and 5V applications. The
MAX7383 features a factory-programmed high-speed
oscillator, a 32.768kHz oscillator, a clock enable input,
and a clock-selector input. The clock output can be
switched at any time between the high-speed clock
and the 32.768kHz clock for low-power operation.
Switchover is synchronized internally to provide glitch-free
clock switching.
Unlike typical crystal and ceramic-resonator oscillator
circuits, the MAX7383 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, the MAX7383 is a good
choice for demanding home appliance and automotive
environments.
The MAX7383 is available with factory-programmed frequencies
ranging from 10MHz to 16MHz. See the full data sheet
for standard frequencies and contact the factory for
custom frequencies and UVLO thresholds.
The MAX7383 is available in a 5-pin SOT23 package.
The MAX7383 operating temperature range is -40°C to
+125°C.
