CONSUMER & INDUSTRIAL DIL XO
Description
Our standard clock oscillators QEN 14-H and QEN 4-H use a high
precision crystal resonator sealed with a 2 points mount on
a hybrid circuit board. There are designed to operate
at temperature up to -40° C to +85° C. These low cost oscillators
are particularly well suited, for microprocessors and outdoor
electronics. The tristate output is ideal for automated test
or frequency switching applications. Both the DIL and half DIL
are able to drive TTL and CMOS loads for more design flexibility.
