General Description
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, 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 as standard, the
MAX7383 is a good choice for demanding home appli-
ance and automotive environments.
The MAX7383 is available with factory-programmed fre-
quencies ranging from 10MHz to 32MHz. See Table 1
for standard frequencies and contact the factory for
custom frequencies. Refer to the MAX7377 data sheet
for frequencies less than 10MHz.
The MAX7383 is available in a 5-pin SOT23 package.
The MAX7383 standard operating temperature range is
-40°C to +125°C. See the
Applications Information
sec-
tion for extended operating temperature range.
