CORPORATION
ULTRA-LOW CURRENT, HIGH-TEMPERATURE REAL TIME CLOCK OSCILLATORS
2.5Vdc and 3.3Vdc - 32.768kHz
Description
Q-Tech’s high temperature real time clock oscillators
consist of a source clock square wave generator and a
miniature round or strip quartz crystal built in a low
profile hermetically ceramic package with gold plated
contact terminals.
The device provides a precision clock for timekeeping for
most down-hole electronic applications by using AT or IT
cut quartz crystals. The design and construction of the
QT581 and QT588 series will make accuracy-
improvement techniques over the traditional RTC with a
32.768kHz quartz tuning-fork crystal, which due to its
parabolic characteristics that do not provide much
accuracy over a wide temperature range. As a result, there
is a gaining or losing up to seconds per day and tens of
minutes per year.
The device is built using high temperature materials and
processes suitable for long life and highest reliability.
