1 / 2 page CX-2V-SM 16kHz to 600kHz MINIATURE SMD CRYSTAL FOR PIERCE OSCILLATORS CX-2V-SM 16kHz to 600kHz MINIATURE SMD CRYSTAL FOR PIERCE OSCILLATORS General Description The miniature CX-2V-SM quartz crystal is a high quality tuning- fork resonator for use in Pierce (single inverter) oscillators. The CX- 2V-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 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 1 LR C C 0 1 1 12 R 1 L 1 1 CC0 Mot ional Resistance Motional Capacitance Motional Inductance Shunt Capacitance Equivalent Circuit Frequency Range: Calibration Tolerance*: Motional Resistance (R ): Motional Capacitance (C ): Quality Factor (Q): Shunt Capacitance (C ): Drive Level: Turning Point (T )**: Temperature Coefficient: Ageing, first year: Shock, survival***: Vibration, survival***: Operating Temperature: Storage Temperature: Process Temperature: 16kHz to 600kHz A, B or C (see table) Figure 1 Max.: 16 ~ 169.9kHz, 2x typ. 170~600kHz, 2.5x typ.
