The MAX7384 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
MAX7384 features a factory-programmed high-speed
oscillator, a 32.768kHz oscillator, a clock enable input,
a clock-selector input, and a µP power-on-reset (POR)
supervisor. 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 MAX7384 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 the MAX7384 is a good
choice for demanding home appliance, industrial, and
automotive environments.
The MAX7384 is available with factory-programmed frequencies
ranging from 10MHz to 16MHz. See Table 1 in the full data sheet
for standard frequencies and contact the factory for
custom frequencies and POR thresholds.
The MAX7384 is available in an 8-pin µMAX® package.
The MAX7384 operating temperature range is -40°C to
+125°C.
