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 stripA quartz crystal built
T
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
CORPORATION
MINIATURE CLOCK OSCILLATORS
1.8 to 5.0Vdc - 300kHz to 160MHz
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).
