IC Clocks are semiconductor integrated circuits designed to generate time

Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency.

Oscillators are devices that are used to generate repetitive signals.

Specialty timers are specialty or proprietary products related to timers and timing devices.

Optical crystals are transparent in different spectral regions, depending upon the crystal material

Liquid crystal display (LCD) modules are used at the component level in place of less efficient displays such as cathode ray tubes (CRTs).

Crystal filters are electronic filters that use monolithic crystals
