WebCrystals. Crystal products are passive components most commonly used as time or frequency references in electronic systems. Consisting of a piezoelectric crystal that … WebApr 13, 2013 · The need was for a crystal that was small and tough enough to use in a watch, but the IC used to divide it down to 1 second pulses had to draw very little current. So the frequency chosen was a power of 2 to keep the divider IC as simple as possible, and 32768Hz was a good compromise. Lower would have required a larger, more fragile …
