The crystal is where timing begins.
A passive resonator paired with your IC's oscillator circuit — from 32.768 kHz tuning forks for real-time clocks to MHz AT-cut crystals for processors and radios. Get the load capacitance right, and everything downstream stays on time.
kHz tuning forks. MHz AT-cut crystals.
32.768 kHz
The classic real-time clock crystal — a tiny tuning fork that resonates at 2¹⁵ Hz, ideal because 32,768 cycles per second can be divided down to a clean 1 Hz tick. Used in every RTC, every watch, every battery-powered timer.
1 – 200 MHz
AT-cut crystals are the workhorse of the timing world — thin slices of quartz cut at a specific angle to deliver excellent frequency stability over temperature. The reference clock for nearly every microcontroller, FPGA, RF transceiver and processor on the market.
From hand-soldered to invisible.
Five generations of modern SMD crystal packaging — each new size halves the footprint without compromising frequency stability. From 5.0 × 3.2 mm industrial down to the world's smallest 1.0 × 0.8 mm.
Three sources. Three positioning tiers.
