Description
To complete our standard QEN 14-H and QEN 4-H, we propose our QEN 49/55-DH
that uses an Ag/Pd hybrid circuit board and a crystal resonator mounted on
3 points in a DIL 14.These low cost oscillators are designed for high vibration resis-
tance clock oscillator and extended temperature range up to -55° C to +125° C.
The QEN 55-DH utilizes HCMOS active circuit technology up to 100 MHz.The same
performances are presented for higher environmental severity in a 14 pins DIL
package under the designation QEN 49-DH.
The tristate output is ideal for automated test or frequency switching applications.
