HIGH-RELIABILITY MINIATURE CLOCK OSCILLATORS
1.8 to 5.0Vdc - 15kHz to 160MHz
Q-TECH
CORPORATION
QT89 (Revision J, January 2011) (ECO #10087)
Description
Q-Tech’s surface-mount QT89 oscillators consist of an IC 5Vdc,
3.3Vdc, 2.5Vdc, 1.8Vdc clock square wave generator and a
round AT high-precision quartz crystal built in a rugged leaded
miniature package. This package is primarily designed for
down-hole applications with 5Vdc or 3.3Vdc supply voltage.
