MAX7377

Silicon Oscillator with Low-Power

Frequency Switching

General Description

Features

● 2.7V to 5.5V Operation

The MAX7377 dual-speed silicon oscillator with reset is

a replacement for ceramic resonators, crystals, crystal

oscillator modules, and discrete reset circuits. The device

provides the primary and secondary clock source for

microcontrollers in 3V, 3.3V, and 5V applications. The

MAX7377 features a factory-programmed high-speed

oscillator, a 32.768kHz oscillator, and a clock selec-

tor 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 inter-

nally to provide glitch-free clock switching.

● Accurate High-Speed 600kHz to 10MHz Oscillator

● Accurate Low-Speed 32kHz Oscillator

● Glitch-Free Switch Between High Speed and Low

Speed at Any Time

● ±10mA Clock-Output Drive Capability

● 2% Initial Accuracy

● ±50ppm/°C Temperature Coefficient

● 50% Duty Cycle

Unlike typical crystal and ceramic resonator oscillator

circuits, the MAX7377 is resistant to vibration and EMI.

The high-output-drive current and absence of highimped-

ance nodes make the oscillator less susceptible to dirty

or humid operating conditions. With a wide operating

temperature range as standard, the MAX7377 is a good

choice for demanding home appliance and industrial

environments.

● 5ns Output Rise and Fall Time

● Low Jitter: 160ps

at 8MHz (No PLL)

(P-P)

● 3mA Fast-Mode Operating Current (8MHz)

● 13μA Slow-Mode Operating Current (32kHz)

● -40°C to +125°C Temperature Range

The MAX7377 is available in factory-programmed fre-

quencies from 32.768kHz to 10MHz. See Table 1 for

standard frequencies and contact the factory for custom

frequencies.
