32.768kHz Crystal Solutions
32.768kHz crystals, traditionally referred to as watch crystals, play an integral part of many modern timing solutions.
Our recommended 32.768kHz crystal solutions included several different form factors to allow the choice of the most up-to-date ultra-miniature packages (CM9V-T1A), and backwards compatibility when considering a re-design involving older technology (GWX-26).
Several of these products, such as the CM7V-T1A and CM8V-T1A, also optionally feature additional application-specific qualifications, such as AEC-Q200 qualification for automotive projects. The GRX-315 comes with full AEC-Q200 qualification as standard.
