| CX MINIATURE CRYSTALS 10kHz to 600kHz MINIATURE QUARTZ CRYSTAL FOR SERIES OSCILLATORS EUROQUARTZ Telephone: +44(0)1460 230000 Fax: +44(0)1460 230001 Email: sales@euroquartz.co.uk Web: www.euroquartz.co.uk CX-1H-03 Page 1 of 2 General Description The CX-1H quartz crystal is a high quality tuning fork resonator designed for use in Series (two cascaded inverters) oscillators. The CX-1H 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 Specification 0.7 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. 1.5W max. @ 10~24.9kHz 3.0W max. @ 25~600kHz Figure 4 -0.035ppm/C 5ppm max. 1,000g 1ms, 1/2 sine 20g rms 10 - 2,000Hz -10~+70C (commercial) -40~+85C (industrial) -55~+125C (military) -55C~+125C Lead to Package temp. not to exceed 175C Glass lid to package seal rim temp. not to exceed 210C 7.6 8.1 Motional Capacitance (C): Quality Factor (Q): 2.0 3.8 3.8 Outline and Dimensions Shunt Capacitance (C): Drive Level: Turning Point (T)**: Temperature Coefficient (k): Ageing, first year: Shock, survival***: Vibration, survival***: Operating Temperature: Storage Temperature: Process Temperature: Equivalent Circuit L1 R1 1 C1 C0 2 L 1 Motional Inductance C 1 Motional Capacitance C0 Shunt Capacitance R 1 Motional Resistance Specifications are typical at 25C unless otherwise indicated. * Closer calibration available ** Other turning point available *** Higher shock and vibration available Conventional Series Oscillator Circuit CX-1H Crystal Calibration Tolerance at 25C Calibration Frequency Range (kHz) 10~74.9 75~169.9 170~249.9 250~600 A Oscillator Buffer 0.003% 0.01% 0.1% 0.005% 0.01% 0.1% 0.01% 0.02% 0.2% 0.02% 0.05% 0.5% B C CX-1H Crystal CX MINIATURE CRYSTALS 10kHz to 600kHz MINIATURE QUARTZ CRYSTAL FOR SERIES OSCILLATORS EUROQUARTZ Telephone: +44(0)1460 230000 Fax: +44(0)1460 230001 Email: sales@euroquartz.co.uk Web: www.euroquartz.co.uk CX-1H-03 Page 2 of 2 Package Handling The CX crystal is hermetically sealed in a ceramic package. Normal handling and soldering precautions for small, low thermal mass parts are adequate when installing or testing CX crystals. The crystals may be wave soldered, taking proper precautions to avoid desoldering the leads. A slow machine rate or too high a pre-heat temperature or solder bath temperature can damage the crystals. Lead to package solder interface temperature should not exceed 175C, and glass lid to package seal rim temperature should not exceed 210C. Should the seal rim temperature exceed these limits the package may lose its hermeticity. Loss of hermeticity results in a decrease of frequency and increase in motional resistance.
