FAE Expert Insights
"The TCXO3225-38M4-10 is our most popular TCXO for cellular applications. The 38.4MHz frequency is the standard reference for most 4G LTE chipsets, and the ±1.0ppm stability meets 3GPP requirements. I've specified this part in numerous cellular module designs with excellent results. The multi-voltage support (1.8V/2.8V/3.3V) is particularly useful for designs with multiple power domains. The price point is very competitive compared to Japanese alternatives, making it attractive for cost-sensitive cellular IoT products. What I appreciate most is the consistent supply and short lead times. For any LTE cellular design, this is my first-choice TCXO recommendation."
Ideal for 4G LTE with multi-voltage support and competitive pricing.

Frequently Asked Questions
What cellular standards does this TCXO support?
The TCXO3225-38M4-10 with ±1.0ppm stability supports all major 4G LTE standards including FDD-LTE (Bands 1-32) and TDD-LTE (Bands 33-46). The 38.4MHz frequency is the standard reference for most LTE baseband processors from Qualcomm, MediaTek, and other vendors. The stability meets 3GPP requirements for cellular operation. This TCXO is also suitable for 3G WCDMA/HSPA applications. For 5G NR applications, the same frequency is used but may require even better stability depending on the specific 5G band and application. The multi-voltage support makes it compatible with various baseband processor I/O voltages.
Suitable for 4G LTE, 3G, and some 5G applications. Contact us for 5G-specific recommendations.
Can this TCXO be used at 1.8V?
Yes, the TCXO3225-38M4-10 supports multiple voltage options including 1.8V, 2.8V, and 3.3V. When ordering, specify the required voltage as the part number suffix (e.g., -1V8 for 1.8V operation). The voltage selection affects the output logic levels - at 1.8V, the CMOS output swings 0V to 1.8V. Power consumption is slightly lower at 1.8V compared to 3.3V. The frequency stability and phase noise performance are maintained across all voltage options. This multi-voltage capability is valuable for designs with multiple power domains, such as smartphones where the baseband may use 1.8V I/O while other circuits use 3.3V.
Specify voltage when ordering. Compatible with 1.8V, 2.8V, and 3.3V systems.
What is the recommended soldering profile for TCXO3225-38M4-10?
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 TCXO3225-38M4-10?
The TCXO3225-38M4-10 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 TCXO3225-38M4-10?
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.
