FT3CNBPM25.0-BULK

Oscillators Overview

The FT3CNBPM25.0-BULK is a temperature-compensated crystal oscillator (TCXO) manufactured by Fox Electronics, operating at a nominal frequency of 25 MHz. It utilizes a 3.2mm x 2.5mm clipped sine wave package and requires a 3.3V supply voltage. The device offers an initial accuracy of ±2 ppm at 25°C and maintains frequency stability within ±2.5 ppm over the -30°C to +85°C industrial temperature range. Key performance metrics include a typical phase noise of -130 dBc/Hz at 1 kHz offset, a start-up time of 3 ms, and a control voltage pull range of ±3 to ±15 ppm. It features low power consumption of 2 mA and supports reflow soldering up to 260°C with MSL level 1 classification.

Oscillators Feature Summary

• Compact 3.2mm x 2.5mm surface-mount footprint designed for space-constrained portable and wearable devices.
• High frequency stability with ±2.5 ppm total frequency tolerance across the industrial temperature range.
• Low power consumption of 2 mA suitable for battery-operated applications.
• Robust anti-interference performance with minimal frequency deviation under voltage or load fluctuations.

Oscillators Applications

• GNSS timing and synchronization systems
• Portable test and measurement instruments
• Compact wireless gateways
• Wearable health monitoring devices

Oscillators Procurement Notes

Verify the specific ordering suffix against the official Fox Electronics datasheet to ensure correct voltage, temperature range, and packaging configuration. Confirm that the BULK packaging format aligns with your assembly line requirements. Ensure compatibility with RoHS and REACH standards if required by your manufacturing process. Cross-reference the pinout configuration, particularly distinguishing between TCXO and VCTCXO versions, to prevent circuit damage during integration.

Oscillators Selection Notes

Select this component when a small form factor is critical alongside moderate precision requirements. The 3.2mm x 2.5mm size reduces board area by approximately 60% compared to traditional 5032 packages. It is suitable for designs requiring fast start-up times and stable operation without external calibration. Consider the ±2.5 ppm stability sufficient for most consumer and light industrial communication protocols.

Oscillators Part Context

This part belongs to the FT3CN series, a family of high-performance TCXOs from Fox Electronics. It serves as a direct replacement for legacy models like the FOX923, offering pin-to-pin compatibility. The series is engineered to provide reliable clock sources for modern compact electronics, balancing size, power efficiency, and frequency accuracy.

Oscillators Replacement Considerations

The FT3CNBPM25.0-BULK is a direct pin-to-pin substitute for the FOX923 series. Verify mechanical dimensions and electrical parameters against existing designs to ensure seamless integration without PCB layout modifications.

Oscillators FAQ

What is the difference between the TCXO and VCTCXO versions in this series?

The standard TCXO version has pins 1 and 2 as GND, pin 3 as output, and pin 4 as supply. The VCTCXO version requires pin 1 to be connected to a control voltage (Vc), typically defaulting to 0.5VDD. Connecting a VCTCXO pin incorrectly to power can cause damage.

Is the FT3CNBPM25.0-BULK suitable for high-temperature automotive environments?

No, this specific model operates within the -30°C to +85°C range. For wider temperature ranges such as -40°C to +105°C, other variants within the FT3CN series must be selected.
