Question

For critical application quartz oscillator is usually contained in container called ___________

(a) Crystal oven

(b) Crystal case

(c) Silicon container

(d) Crystal container

I had been asked this question in a national level competition.

The doubt is from Crystal Oscillator-2 in chapter Oscillators of Analog Circuits

Answer 1

The correct option is (a) Crystal oven

The best I can explain: For critical applications, the quartz oscillator is mounted in a temperature-controlled container. It is called a crystal oven, and can also be mounted on shock absorbers to prevent perturbation.
