CORPORATION
EXTREME CURRENT, HIGH-TEMPERATURE REAL TIME CLOCK DRIVER OSCILLATORS
2.5Vdc and 3.3Vdc - 32.768kHz
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 on
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.

[Ask TI] How many CLKs are needed for MSP430 IO read and write operations?
I would like to ask TI experts, how many CPU clock cycles are needed to complete the MSP430 IO write operation, such as P1OUT |= 0x10, and the read operation, such as IOValue = P1IN ?...

Has anyone used Ad565?
I recently needed to use high-speed DA conversion, so I went to the electronics market and bought a few Ad565AJD (24-pin direct plug) chips. I built a simple circuit and found that it didn't work at a...
