TFETBLJANF-19.440000

Oscillators Overview

The Taitien TFETBLJANF-19.440000 is a temperature-compensated crystal oscillator (TCXO) operating at 19.44 MHz. It features CMOS output and through-hole mounting. The device operates on a 3.3V supply with a maximum current consumption of 20mA. Frequency stability is specified at ±1ppm over an operating temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Temperature-compensated crystal oscillator design for stable frequency performance across varying thermal conditions.
• CMOS digital output interface suitable for direct connection to logic circuits without additional coupling components.

Oscillators Applications

• Telecommunications base stations requiring precise clock synchronization
• Network infrastructure equipment needing high-frequency stability
• Test and measurement instruments demanding accurate timing references

Oscillators Procurement Notes

Verify the specific package type and pin configuration against the official datasheet before integration, as through-hole variants may differ from surface-mount counterparts in the same series. Confirm that the ±1ppm stability rating aligns with system requirements under full operating temperature extremes. Ensure supply voltage matches the 3.3V specification to avoid performance degradation or damage.

Oscillators Selection Notes

Select this component when through-hole mounting is required for mechanical robustness in industrial environments. The CMOS output simplifies circuit design by eliminating the need for AC coupling capacitors often necessary with sine wave outputs. Consider the ±1ppm stability limit for applications sensitive to long-term drift, ensuring it meets the jitter and phase noise specifications of the target system.

Oscillators Part Context

This model belongs to Taitien’s TCXO family, distinguished by its through-hole construction compared to the SMD variants like the TSETTL series. It shares the 19.44 MHz frequency point but differs in physical form factor and potentially in thermal compensation characteristics due to the different packaging technology used for leaded assemblies.

Oscillators Replacement Considerations

Cross-reference with other manufacturers offering 19.44 MHz TCXOs in DIP packages. Verify pin compatibility and electrical parameters such as supply current and stability before substitution. Note that while frequency and output type may match, thermal compensation curves and aging rates can vary significantly between brands.
