32.768, with you and me

The 32.768kHz crystal is widely used in circuits with timing needs, and the clocks we use every day in watches, cell phones and computers are evolved from it. It accompanies us through every second of our lives.

The frequency of 32.768kHz crystal is a real-time clock crystal, commonly known as watch crystal, also known as tuning fork crystal. Its ubiquitous famous in the field of frequency components and main role is to generate timing circuit reference signal, accurate to one second timing.

Why 32.768kHz is so important? 32.768kHz is a standard frequency, 32.768kHz clock crystal oscillation signal generated by the quartz clock internal frequency divider for 15 times to get 1Hz second signal, that is, the clock second pin runs every second, the quartz clock internal frequency divider can only carry out 15 times,15 times after the frequency divider is Not 1Hz seconds signal if replaced by another frequency crystal, then the clock will not be accurate.

The iconic size in the 32.768kHz watch crystal are

DIP: 3*8mm, 2*6mm.

SMD: 2.0*1.2mm, 3.2*1.5 mm, 6.9*1.4 mm, 3.8*8 mm, 2*6 mm.

The common load capacitance is: 6pF, 7pF, 9pF, 12.5pF.

WTL's best selling tuning fork crystal is WX1 series 3.2*1.5/2/SMD, which has small size, high stability, and environmental performance in line with ROHS/lead-free standards, the advantages are: sufficient capacity, fast delivery, reasonable price, and high customer repurchase rate.
