CX MINIATURE CRYSTALS 10kHz to 600kHz MINIATURE QUARTZ 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-03 Page 1 of 2 General Description The CX-1V quartz crystal is a high quality tuning fork resonator designed for use in Pierce (single inverter) oscillators. The CX-1V is hermetically sealed in a rugged, miniature ceramic package, a quarter the size of an eight pin dual-in-line package. The crystal is manufactured utilizing a photo-lithographic process, ensuring consistency and repeatability of electrical characteristics.        Miniature tuning-fork design High shock resistance Designed for low-power applications Compatible with hybrid packaging Low ageing Full military environmental testing available Ideal for battery powered applications Specification Frequency Range: Calibration Tolerance*: Motional Resistance (R): 10kHz to 600kHz A, B, or C (see table below) Figure 1 2x Typ. @ 10~169.9kHz 2.5x Typ. @170~600kHz Figure 2 Figure 3 (Minimum is 0.25x Typ.) 2.0pF max. 0.5µW max. @ 10~24.9kHz 1.0µW max. @ 25~600kHz Figure 4 -0.035ppm/°C2 ±5ppm max. 1,000g 1ms, ½ sine 20g rms 10 - 2,000Hz -10°~+70°C (commercial) -40°~+85°C (industrial) -55°~+125°C (military) -55°C~+125°C Lead to Package temp. not to exceed 175°C Glass lid to package seal rim temp. not to exceed 210°C 0.7 7.6 8.1 Motional Capacitance (C): Quality Factor (Q): Shunt Capacitance (C): Drive Level: Turning Point (T)**: Temperature Coefficient (k): Ageing, first year: Shock, survival***: Vibration, survival***: Operating Temperature: 2.0 3.8 3.8 Outline and Dimensions Equivalent Circuit L1 R1 1 C1 C0 2 Storage Temperature: Process Temperature: L 1 Motional Inductance C 1 Motional Capacitance C0 Shunt Capacitance R 1 Motional Resistance Conventional HCMOS Pierce Oscillator Circuit Rf Amplifier Specifications are typical at 25°C unless otherwise indicated. * Closer calibration available ** Other turning point available *** Higher shock and vibration available CX-1V Crystal Calibration Tolerance at 25°C Buffer Osc.
