HIGH-RELIABILITY CMOS OR TTL MINIATURE CLOCK OSCILLATORS
1.8 to 5.0Vdc - 15kHz to 162.5MHz
Description
Q-Tech’s surface-mount QT94 oscillators consist of a
5Vdc, 3.3Vdc, 2.5Vdc, 1.8Vdc CMOS or TTL 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 5 x 7 mm COTS
oscillator.
