CRYSTAL OSCILLATOR - XO

QEN 49/55-BH/CH

FULL MILITARY DIL XO

These high perform ance DIL clock oscillators are designed for high vibration

and extended tem perature range up to -55° C to +125° C.

The QEN55-BH/CH utilize HCMOS active circuit technology up to 40 MHz and

an ACMOS technology up to 70 MHz. The crystal resonator is m ounted on

3 points on a true hybrid alum ina substrate with gold printed circuit path

and is well suited for m ilitary and avionics applications. The sam e perfor-

m ances are presented for higher environm ental severity in a 14 pins DIL

package under the designation QEN49-BH/CH.

In the overlapping range between 14 MHz and 40 MHz, the choice depends

on the other available options such as duty cycle tolerance and the tristate

output.
