LFTCXO070346BULK

Overview

The LFTCXO070346BULK is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 25 MHz with a supply voltage range of 2.8V to 3.63V. The device features an HCMOS output format and is housed in a compact 2.50mm x 2.00mm surface-mount package. It supports a maximum load capacitance of 15pF for CMOS outputs.

Feature Summary

• Integrates temperature compensation circuitry for stable frequency performance across varying thermal conditions.
• Utilizes a miniature surface-mount package design suitable for space-constrained electronic assemblies.
• Provides a standard HCMOS logic output compatible with digital system interfaces.

Applications

• Portable consumer electronics requiring precise timing references
• Industrial control systems operating in variable temperature environments
• Communication equipment needing stable clock signals

Procurement Notes

Verify the specific frequency tolerance and aging specifications required for your application against the official datasheet, as these parameters can vary significantly between different part number suffixes within the same series. Confirm that the 2.50mm x 2.00mm footprint matches your PCB layout constraints. Ensure the HCMOS output voltage levels are compatible with your downstream logic inputs before finalizing the procurement order.

Selection Notes

Select this component when a small form factor TCXO is needed for applications requiring better stability than standard crystals but without the complexity of VCXOs. Consider the 2.8V minimum supply voltage if designing low-power battery-operated devices. Evaluate the trade-off between the compact size and potential sensitivity to mechanical stress compared to larger packages.

Part Context

This part belongs to the LFTCXO series from IQD Frequency Products, which specializes in miniature temperature-compensated crystal oscillators. The series is designed to replace larger through-hole or standard SMD oscillators in modern miniaturized electronics. It represents a solution for applications where size reduction is critical while maintaining frequency accuracy over temperature.

Replacement Considerations

Direct substitutes may include other 25MHz TCXOs in similar 2.5x2.0mm packages from manufacturers like Rakon or TXC. Verify pin compatibility and electrical specifications carefully, as output drive strength and supply voltage ranges may differ between competing brands.
