The tuning fork crystal as it is used in watches is something like the “classic” among the quartz crystals. Its frequency is always exactly 32.768 kHz. But why this value? The answer to this question can be found in the history of quartz crystals. Bell Telephone Laboratories, the former research department of today’s telecommunications group

The new crystal oscillators JO22 and JO32

If you want to equip your product with an oscillator, and there is hardly an electronic application that can do without, you must define the operating voltage of your application first because oscillators are usually “calibrated” to a specific voltage value. A precise frequency requires a constant and predetermined working voltage. If deviations occur, the
