CX MINIATURE CRYSTALS 10kHz to 600kHz MINIATURE SMD CRYSTAL FOR PIERCE OSCILLATORS EURO QUARTZ Telephone: +44(0)1460 230000 Fax: +44(0)1460 230001 Email: sales@euroquartz.co.uk Web: www.euroquartz.co.uk CX-1V-SM CX-1V-SM Page 1 of 2 General Description The miniature CX-1V-SM quartz crystal is a high quality tuningfork resonator for use in Pierce (single inverter) oscillators. The CX1V-SM is hermetically sealed in a rugged, leadless ceramic package. The crystal has been designed for surface-mounting on printed circuit boards or hybrid circuits. The CX-1-SM crystal is manufactured using a photo-lithographic process, yielding consistently high quality production parts.        Miniature tuning-fork design High shock resistance Designed for low-power applications Compatible with hybrid or PC board packaging Low ageing Full military environmental testing available Ideal for battery operated applications Specification Frequency Range: Calibration Tolerance*: Motional Resistance (R): Motional Capacitance (C): Quality Factor (Q): 10kHz to 600kHz A, B or C (see table) Figure 1 Max.: 10 ~ 169.9kHz, 2x typ. 170~600kHz, 2.5x typ.
