Quartz Crystal :
General description
Crystals are realized with NT cut, in order to achieve low resonance frequency values (30KHz/80KHz). Widely used to generate internal time reference in PC, Mobile phones, microprocessors applications. 40KHz is standard frequency for ultra-sounds generators. 77.5KHz is, instead used to phase in lock with European broadcast time signal. Such crystals are also adopted with battery supplied systems, when extremely low power consumption is needed, for example during stand-by
ROHS Compliant
