The JITO-2 Phase
Jitter Advantage
Phase Jitter has long been recognized as
one of the most critical and defining
parameters in the design and application
of oscillators. Fox JITO
-2 Just-In-Time
Oscillators meet the need for more
tightly controlled phase jitter. As
detailed in the technical data below,
JITO
-2 oscillators offer a 67% reduction
in phase jitter over competitive
programmed oscillators.
And in certain frequency bands, the
phase jitter characteristics of our
JITO
-2 oscillators compare favorably
to fixed frequency oscillators.
The dramatically reduced phase jitter
of Fox JITO
-2 oscillators can make your
systems less prone to the introduction of
bit errors with microprocessors and
increase the reliability of any data
sensitive application.
If phase jitter is a critical specification
for your application, specify JITO
-2 to
be sure.

Cycle to Cycle Phase Jitter measurements on our JITO
-2 oscillators are performed
with a Tektronix TDS 784C Digital Oscilloscope using the histogram function.
With the trigger set at the midpoint of the rising edge, a histogram of the
horizontal deviation of the first rising edge from the trigger point is constructed.
The peak to peak distribution and standard deviation (Sigma or RMS) is derived
from this histogram. This is the "measured" cycle to cycle phase jitter, peak to
peak and RMS. The same measurement is then taken at the trigger point to
determine "trigger phase jitter" (typically 60 ~ 80pS p-p/10 ~ 13pS RMS).
The trigger phase jitter is then subtracted from the measured phase jitter one
cycle out to determine cycle to cycle phase jitter, peak to peak and RMS.
Typical phase jitter measurements listed here are based on subtracting the
lesser, 60pS p-p/10pS RMS, value from all measured values.
Typical phase jitter values for the frequency range of 50MHz ~ 250MHz are
listed below:
