FAE Expert Insights
"The TCXO3225-26M-05 is our premium TCXO for GPS applications, and it delivers excellent performance at a competitive price point. I've used this part in numerous GPS tracker and navigation device designs with excellent results. The ±0.5ppm stability ensures fast TTFF (Time To First Fix) and accurate positioning. What impresses me is the consistent performance across different production batches - important for high-volume manufacturing. The phase noise performance is comparable to much more expensive Japanese TCXOs. For customers designing GPS-enabled products, this TCXO provides the right balance of performance and cost. I recommend it for any GPS application requiring <1ppm stability."

Frequently Asked Questions
Is this TCXO suitable for GPS applications?
Yes, the TCXO3225-26M-05 with ±0.5ppm stability is specifically designed for GPS and GNSS applications. GPS receivers require high-stability timing references for accurate satellite signal acquisition and tracking. The ±0.5ppm stability ensures that the receiver can maintain lock on weak satellite signals and achieve accurate positioning. The 26MHz frequency is the standard reference frequency for most GPS chipsets. The low phase noise (-135dBc/Hz @ 1kHz) helps achieve fast TTFF (Time To First Fix). This TCXO has been successfully deployed in various GPS trackers, navigation devices, and location-based services. For high-precision GPS (RTK, surveying), consider OCXO products with even better stability.

What is the power consumption of this TCXO?
The TCXO3225-26M-05 consumes approximately 2-3mA typical at 3.3V, which is higher than standard crystal oscillators due to the temperature compensation circuitry. The power consumption is relatively constant across temperature. For battery-powered applications, this power consumption should be factored into the overall power budget. Some TCXOs have a standby mode that reduces power consumption when the oscillator is not needed. The higher power consumption is the trade-off for achieving excellent temperature stability. For ultra-low-power applications, consider using a standard XO with good temperature characteristics or implementing software compensation. Contact us for power-sensitive application recommendations.
Factor 2-3mA into power budget. Contact us for low-power timing alternatives if needed.
What is the recommended soldering profile for TCXO3225-26M-05?
Standard reflow soldering profile per JEDEC J-STD-020 is recommended. Peak temperature should not exceed 260°C for Pb-free solder. Preheat at 150-180°C for 60-90 seconds. Soak at 217°C for 60-90 seconds. Peak at 245-260°C for 20-40 seconds. Allow adequate cooling time. Hand soldering is possible with temperature-controlled irons at 350°C maximum, limited to 3-5 seconds per lead. Avoid thermal shock by not exceeding 4°C/second heating/cooling rates. Washable flux can be used but thorough cleaning is recommended. Follow IPC-A-610 for acceptance criteria.
Use standard Pb-free reflow profile. Contact us for specific soldering recommendations.
What is the MTBF of TCXO3225-26M-05?
The TCXO3225-26M-05 has an MTBF (Mean Time Between Failures) of >100 million hours at 25°C operating temperature, calculated per Telcordia SR-332. This corresponds to a FIT rate of <10 failures per billion device-hours. Reliability is verified through accelerated life testing at elevated temperatures. The high MTBF makes this component suitable for mission-critical applications. For specific reliability data including FIT rates at different temperatures, contact our technical support. Burn-in screening is available for high-reliability applications.

What is the ESD sensitivity rating of TCXO3225-26M-05?
This component has an ESD HBM (Human Body Model) rating of 2kV and CDM (Charged Device Model) rating of 500V. While this provides reasonable protection, standard ESD precautions should always be followed during handling and assembly. Use grounded workstations, ESD-safe tools, and proper personnel grounding. Avoid touching pins directly. Store components in ESD-safe packaging until ready for use. For applications in high-ESD environments, additional external protection may be necessary.
