DESCRIPTION
CX-2V crystals are high quality tuning fork crystals intended for use in Pierce (single inverter) oscillator circuits. The crystal is hermetically sealed and rugged. OUTLINE & DIMENSIONS Specifications stated are typical at 25°C unless otherwise indicated. Specifications may change without notice. Frequency Range: 16.0kHz to 600.0kHz Functional Mode: Tuning Fork (Flexure) Standard Calibration Tolerance*: A, B or C Motional Resistance (R1): Figure 1 Max = 16~24.9kHz, 2x typical 25~600kHz, 2.5x typical Motional Capacitance (C1): Figure 2 Quality Factor (Q): Figure 3 Min. is 0.25x typical Shunt Capacitance (C0): 2.0pF max. Drive Level 16~24.9kHz: 0.5µW max. 25~600.0kHz: 1.0µW max. Turning Point (T0): Figure 4 Temperature Coefficient (k): -0.035ppm/°C 2 Ageing, first year: 5ppm max. Shock, survival*: 1,500g, 0.3ms, ½ sine Vibration, survival***: 10g rms, 20~2000Hz Operating Temperature Range Commercial: -10° to +70°C Industrial: -40° to +85°C Military: -55 to +125°C Storage Temperature Range: -55° to +125°C Maximum Process Temperature: See package handling note SPECIFICATION 75~169.9 170~249.9 STANDARD CALIBRATION TOLERANCE
