Speed-Switching Clock Generator
with Power Fail
General Description
The MAX7391 replaces ceramic resonators, crystals,
and supervisory functions for microcontrollers in 3.3V
and 5V applications.
Features
♦ Robust Microcontroller Clock and Supervisory
Functions in a Single Package
♦ Integrated Reset and Power-Fail Functions
♦ Speed Select
The MAX7391 provides a clock source, reset, and
power-fail functions. The programmable power-fail func-
tion provides early warning of power failure and is con-
♦ +2.7V to +5.5V Operation
figurable to detect either an external voltage or the V
supply to the device.
CC
♦ Factory-Trimmed Oscillator
♦ Reset Valid Down to 1.1V Supply Voltage
♦ ±1ꢀmꢁ Clock-Output Drive Current
♦ ±±4 Total ꢁccuracy ꢂor -±ꢀ0C to +1250C
The clock output can be switched between normal and
half-speed operation. This functionality allows the micro-
controller to operate at reduced power and may be
used to extend the time available to perform house-
keeping tasks, such as writing data to flash during a
power failure. Connecting the power-fail output to the
SPEED input reduces clock speed automatically during
power-fail events.
♦ ±2.754 Total ꢁccurac ꢂor ꢀ0C to +ꢃ50C
♦ 5.5mꢁ Operating Current (12MHz Version)
♦ -±ꢀ0C to +1250C Temperature Range
♦ Surꢂace-Mount Package
The MAX7391 clock output is factory programmed to a
frequency in the 1MHz to 16MHz range. Four standard
frequencies are available. Other frequencies are avail-
able upon request. The maximum operating supply cur-
rent is 5.5mA (typ) with a clock frequency of 12MHz.
♦ 1MHz to 16MHz Factory Preset Frequency Range
Unlike typical crystal and ceramic resonator oscillator
circuits, the MAX7391 is resistant to EMI and vibration,
and operates reliably at high temperatures. The high-
output drive current and absence of high-impedance
nodes make the oscillator invulnerable to dirty or humid
operating conditions.

Clock Output (CLOCK)
The push-pull clock output (CLOCK) drives a ground-
connected 1kΩ load or a positive supply connected
500Ω load to within 300mV of either supply rail. CLOCK
remains stable over the full operating voltage range and
does not generate short output cycles during either
power-on or power-off. A typical startup characteristic is
shown in the Typical Operating Characteristics section.
Detailed Description
The MAX7391 replaces ceramic resonators, crystals,
and supervisory functions for microcontrollers in 3.3V
and 5V applications.
The MAX7391 provides a clock source, reset, and
power-fail functions. The power-fail output provides
early warning of power failure. The power-fail threshold
is configurable to detect either an external voltage or

The clock output can be switched between normal and

microcontroller to operate at reduced power and may
be used to extend the time available to perform house-

power failure. Connecting the power-fail output (PFO)
to the SPEED input reduces clock speed automatically
during power-fail events.
Reset
The reset function drives the microcontroller reset input
to prevent operation in the cases of the initial power-on
setting, low power-supply voltages, and the failed
watchdog operations. Three reset output versions are
available: push-pull RST, push-pull RST, and open-drain
The integrated reset provides the power-supply monitor-
ing functions necessary to ensure correct microcontroller
operation. The reset circuit has built-in power-supply
transient immunity and provides both power-on reset
and power-fail or brownout reset functionality. Two stan-
dard factory-trimmed reset levels are available.

Power-Supply Considerations
Applications Information
Interfacing to a Microcontroller
Clock Input
The MAX7391 operates with power-supply voltages in
the 2.7V to 5.5V range. Good power-supply decoupling
is needed to maintain the power-supply rejection per-
The clock output is a push-pull, CMOS logic output,
which directly drives any microprocessor (µP) or micro-
controller (µC) clock input. There are no impedance-
matching issues when using the MAX7391. Operate the
MAX7391 and µC (or other clock input device) from the
same supply voltage level. Refer to the microcontroller
data sheet for clock-input compatibility with external
clock signals. Table 3 lists clock output frequency.
formance of the MAX7391. Bypass V
to GND with a
CC
0.1µF surface-mount ceramic capacitor. Mount the
bypass capacitor as close to the device as possible. If
possible, mount the MAX7391 close to the microcon-
troller’s decoupling capacitor so that additional decou-
pling is not required.
A larger-value bypass capacitor is recommended if the
MAX7391 is to operate with a large capacitive load.
Use a bypass capacitor value of at least 1000 times
that of the output load capacitance.
The MAX7391 requires no biasing components or load
capacitance. When using the MAX7391 to retrofit a
crystal oscillator, remove all biasing components from
the oscillator input.
Output Jitter
The MAX7391’s jitter performance is given in the
Electrical Characteristics table as a peak-to-peak value
obtained by observing the output of the device for 20s
with a 500MHz oscilloscope. Jitter measurements are
approximately proportional to the period of the output
frequency of the device. Thus, a 4MHz part has approx-
imately twice the jitter value of an 8MHz part.

The jitter performance of all clock sources degrades in
the presence of mechanical and electrical interference.
The MAX7391 is immune to vibration, shock, and EMI
influences, and thus provides a considerably more
robust clock source than crystal- or ceramic-resonator-
based oscillator circuits.
