Do you know?
A 32.768 kHz tuning fork crystal is a crystal resonator oscillating at 32.768 kHz, a frequency chosen because it’s a power of 2 (2^15). This enables easy division down to a 1 Hz signal, ideal for timekeeping. Made from specially cut quartz, these crystals offer high tolerance, stability, and resistance to environmental factors.
Beyond just timekeeping, they are also used as clock sources in various digital circuits including communication equipment, microcontrollers, and embedded systems. Their low-power consumption makes them essential in portable, energy-sensitive devices such as wireless communication, wearables, and IoT applications.
