MINIATURE CLOCK OSCILLATORS
1.8 to 5.0Vdc - 500kHz to 160MHz
Description
Q-Tech’s surface mount 5 X 7 mm oscillator series consist
of an IC 5Vdc, 3.3Vdc, 2.5Vdc, 1.8Vdc clock square
wave generator and a miniature stripAT quartz crystal built
in a low profile ceramic package with thru-hole, formed
lead, or gull wing. This is the smallest package Q-Tech
has ever offered for High Reliability applications.. The
lead forming can provide a solution for many applications
that require additional lead attachment from an outside
subcontractor.

Jitter And Phase Noise
As data rate increases, effect of jitter becomes critical
with its budget tighter. Jitter is the deviation of a timing
event of a signal from its ideal position. Jitter is
complex and is composed of both random jitter (RJ) and
deterministic jitter (DJ) components.
Random Jitter (RJ) is theoretically unbounded and
Gaussian in distribution, while Deterministic Jitter (DJ)
is bounded and does not follow any predictable
distribution.
Q-Tech utilizes the EZJIT Plus jitter analysis software
with Noise reduction software that supports Agilent
Infinium real-time oscilloscope. Measure at its
maximum sampling rate 40Gs/s and memory depth, we
can separate the signal’s aggregate total jitter into
Random Jitter (RJ) and Deterministic Jitter (DJ).
Since Random Jitter is unbounded and Gaussian in
style, the Total Jitter is a function of Bit Error Rate
(BER).
TJ = RJ + DJ

MINIATURE CLOCK OSCILLATORS
1.8 to 5.0Vdc - 500kHz to 160MHz
Phase noise is measured in the frequency domain, and is expressed as a ratio of signal power to noise power measured in a 1Hz bandwidth
at an offset frequency from the carrier, e.g. 10Hz, 100Hz, 1kHz, 10kHz, 100kHz, etc. Phase noise measurement is made with an Agilent
E5052A Signal Source Analyzer (SSA) with built-in outstanding low-noise DC power supply source. The DC source is floated from the
ground and isolated from external noise to ensure accuracy and repeatability.
In order to determine the total noise power over a certain frequency range (bandwidth), the time domain must be analyzed in the frequency
domain, and then reconstructed in the time domain into an rms value with the unwanted frequencies excluded. This may be done by
converting L(f) back to Sφ(f) over the bandwidth of interest, integrating and performing some calculations.
Phase Noise and Phase Jitter Integration
The value of RMS jitter over the bandwidth of interest, e.g. 10kHz to 20MHz, 10Hz to 20MHz, represents 1 standard deviation of phase
jitter contributed by the noise in that defined bandwidth.
Figure below shows a typical Phase Noise/Phase jitter of a QT82LD10M, 3.3Vdc, 32MHz and QT83HCD10M, 5.0Vdc, 40MHz clock
at offset frequencies 10Hz to 1MHz, and phase jitter integrated over the bandwidth of 12kHz to 1MHz.
