SPECIFYING SURFACE MOUNT TEMPERATURE COMPENSATED CRYSTAL OSCILLATORS TCXOs)
typical surface mount TCXO specification reads like this: 13.0MHz CFPT-635 Frequency Model Number Frequency Stability Operating Temperature Range Packaging Additional Text Code (for non-standard product) following notes define each element specification. Frequency Frequency normally specified kilohertz (kHz) 999.9kHz megahertz (MHz) from 1.0MHz. computer-generated transaction documents follow this standard convention automatically. TCXO frequency should described seven significant figures. seven significant figures used, assume that figure that might follow those given taken zero. Thus frequency given 16.6MHz will taken 16.60 16.6666. Please contact sales office details developed frequencies. Model Number model number incorporates information which describes output compatibility holder style. Frequency Stability frequency stability TCXO frequency change over Operating Temperature Range. tight tolerance applications necessary apply frequency offset 25°C order centralise frequency/temperature characteristic nominal frequency. applicable this will stated individual datasheet. following codes apply frequency stability: ±0.3ppm ±0.8ppm ±1.5ppm ±0.25ppm ±0.5ppm ±1.0ppm ±2.0ppm ±2.5ppm ±3.0ppm ±5.0ppm ±10.0ppm ±0.2ppm ±15.0ppm Frequency Trimming order meet their specification over their full operating temperature range, close tolerance TCXOs often adjusted have frequency offset room temperature. Adjustment mechanical trimmers such TCXOs should attempted, therefore, unless facilities exist measure their frequency over their full operating temperature range Operating Temperature Range Although general TCXO's will continue operate ouside their normal temperature range with degradation frequency stability, damage result temperatures reached excessive. following codes apply Operating Temperature Ranges: 70°C 75°C 95°C 50°C 60°C 70°C 75°C Packaging Code Tape Reel packaging available option many products outlined TCXO Chapter.

Standard Frequency Tolerances Stabilities Please refer individual datasheets each TCXO. Offset Frequency frequency difference, positive negative, (expressed which should added nominal frequency when setting oscillator specified temperature (usually purpose minimise frequency deviation over entire operating temperature range. Each oscillator will have it's offset frequency marked case. following example dotted line shows that oscillator nominal frequency 25°C, frequency deviates from -1.7 +0.3 over temperature range. setting frequency 25°C specified offset frequency, overall frequency deviation reduced ±1.0
