LFTCXO077231REEL

Overview

The LFTCXO077231REEL is a Temperature Compensated Crystal Oscillator (TCXO) from IQD Frequency Products, operating at a nominal frequency of 38.4 MHz. It features a clipped sine wave output format and operates on a single supply voltage of 1.2 V. The device offers high frequency stability of ±500 ppb and includes an enable/disable function for power management. Packaged in a compact 4-SMD, No Lead form factor, it is designed for surface mount applications requiring precise timing in space-constrained environments.

Feature Summary

• Integrated temperature compensation ensures stable frequency performance across varying thermal conditions.
• Low supply voltage operation supports energy-efficient designs in portable devices.
• Built-in enable and disable functionality allows for dynamic power control.

Applications

• Mobile communication handsets
• Wireless local area network modules
• Portable consumer electronics

Procurement Notes

Verify the specific reel packaging configuration and ensure compatibility with automated pick-and-place equipment during assembly. Confirm that the 1.2V supply rail meets the current requirements for the clipped sine wave output stage. Check for any recent product change notifications regarding pinout or material composition updates before finalizing the bill of materials.

Selection Notes

Select this component when sub-ppm stability is required within a minimal footprint. The 1.2V supply requirement distinguishes it from standard 1.8V or 3.3V oscillators, making it suitable for low-voltage logic families. Ensure the host circuit can accommodate the clipped sine wave output impedance without additional buffering if signal integrity is critical.

Part Context

This part belongs to the LFTCXO series of surface-mount TCXOs from IQD Frequency Products. It utilizes crystal resonator technology and is distinguished by its ultra-low voltage operation compared to other members of the family that may support higher voltages. The REEL suffix indicates bulk tape packaging for high-volume manufacturing.

Replacement Considerations

Direct substitutes include other 38.4 MHz TCXOs with similar ±500 ppb stability and 1.2V supply requirements. Verify package dimensions and pin assignments against competitors like SiTime or Epson to ensure mechanical interchangeability.
