Detailed Description
The MAX7375 is a replacement for ceramic resonators,
crystals, and crystal oscillator modules as the clock
source for microcontrollers and UARTs in 3V, 3.3V, and
5V applications. The MAX7375 is an integrated oscilla-
tor, supplied at specific frequencies just like crystals
and resonators. A variety of popular standard frequen-
cies are available. No external components are
required for setting or adjusting the frequency.
Supply Voltages
The MAX7375 has been designed for use in systems
with nominal supply voltages of 3V, 3.3V, or 5V and is
specified for operation with supply voltages in the 2.7V
to 5.5V range. Operation outside this range is not guar-
anteed. See the
Absolute Maximum Ratings
table for
limit values of power-supply and pin voltages.
Oscillator
The clock output is a push-pull configuration and is
capable of driving a ground-connected 1k
load or a
positive supply connected 500
load to within 300mV
of either supply rail. The clock output remains stable
over the full operating voltage range and does not gen-
erate short output cycles during either power on or
power off. A typical startup characteristic is shown in
the
Typical Operating Characteristics
section.
Output Jitter
The MAX7375’s jitter performance is given in the
Electrical Characteristics
table as a peak-to-peak value
obtained by observing the output of the MAX7375 for
20s with a 500MHz oscilloscope. Jitter measurements
are approximately proportional to the period of the out-
put frequency of the device. Thus, a 4MHz part has
approximately 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 MAX7375 is relatively immune to vibration, shock,
and EMI influences and thus provides a considerably
more robust clock source than crystal- or ceramic-res-
onator-based oscillator circuits.
