DESCRIPTION
CX3HSM crystals consist of a high quality tuning fork resonator in a rugged, hermetically sealed ceramic package. CX3HSM crystals are intended for use in Series (two cascaded inverters) oscillator circuits. Specifications stated are typical at 25°C unless otherwise indicated. Specifications may change without notice. Frequency Range: 18.0kHz to 600.0kHz Standard Calibration Tolerance1: see table Motional Resistance (R1): Figure 1 Max = 18~25kHz, 2 x typical 25~600kHz, 2.5x typical Motional Capacitance (C1): Figure 2 Quality Factor (Q): Figure 3 Min. is 0.25x typical Shunt Capacitance (C0): 1.8pF max. Drive Level 18~24.9kHz: 1.5µW max. 25~600.0kHz: 3.0µW max. Turning Point (T0)2: Figure 4 Temperature Coefficient (k): -0.035ppm/°C 2 Ageing, first year: 5ppm max.
