Silicon Oscillator with Low-Power Frequency
Switching and Reset Output
General Description
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-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 pro-
vide 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 oper-
ating temperature range as standard, the MAX7384 is a
good choice for demanding home appliance, industrial,
and automotive environments.
The MAX7384 is available with factory-programmed fre-
quencies ranging from 10MHz to 16MHz. See Table 1
for standard frequencies and contact the factory for
custom frequencies. Refer to the MAX7378 data sheet
for frequencies less than 10MHz.
The MAX7384 is available in an 8-pin µMAX
®
package.
The MAX7384 standard operating temperature range is
-40°C to +125°C. See the
Applications Information
sec-
tion for extended operating temperature range.
