Silicon Oscillator with Low-Power  
Frequency Switching  
General Description  
Features  
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.
