HIGH-RELIABILITY LVPECL OR LVDS MINIATURE CLOCK OSCILLATORS
Description
Q-Tech’s surface-mount QT93 series oscillators consist of
a 2.5Vdc and 3.3Vdc differential PECL or LVDS output
oscillator IC and a round AT high-precision quartz crystal
built in a rugged surface-mount ceramic miniature
package. It was designed to be replaceable and
retrofitable into the footprint of a 7 x 5mm COTS
LVPECL or LVDS oscillator.
