Silicon Oscillator with Low-Power Frequency

Switching and Reset Output

General Description

Features

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.

♦ 2.7V to 5.5V Operation

♦ High-Speed Oscillator from 10MHz to 16MHz

Low-Speed 32kHz Oscillator

Glitch-Free Clock-Speed Switching

♦ Integrated POR

♦ ±10mA Clock-Output Drive Capability

♦ 2.5% Initial Accuracy

♦ ±50ppm/°C Frequency Drift

♦ 50% Duty Cycle

♦ 5ns Output Rise and Fall Time

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.

♦ Low Jitter: 80ps

at 16MHz

♦ 4mA Operating Current at 16MHz

♦ 13µA, 32kHz Operating Current

♦ -40°C to +125°C Temperature Range

OUTPUT

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.
