Timing devices are passive components that generate clock signals that utilize the piezoelectric effect. Used in all types of electrical equipment such as mobile phones, wearable devices, and AV / PC applications.
Lineup

MEMS Resonator
Murata’s MEMS Resonator is an element that uses the piezoelectric effect to generate a constant frequency from its mechanical resonance.
Ideal for small IoT devices, communication modules, medical equipment, and industrial equipment. Works in harmony with semiconductor IC chips when mounted, and can be incorporated into ICs.

Crystal Unit
A Crystal Unit is an element that uses the piezoelectric effect of quartz to generate a constant frequency from its mechanical resonance.
Applied to a wide range of applications from satellite communication and mobile communication equipment to automobiles, televisions, personal computers, and information appliances such as DVD equipment.

Ceramic Resonator (CERALOCK)
A Ceramic Resonator (CERALOCK) is an resonator that utilizes the mechanical resonance of piezoelectric ceramics, or polycrystalline materials.
Applied to a very wide range of applications such as automobile electrical components, communication equipment, PC-related equipment, medical / healthcare equipment, and home appliances.
