LFTCXO075796

Overview

The LFTCXO075796 is a temperature-compensated crystal oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 19.2 MHz with a frequency stability of 0.28 ppm. The device utilizes a clipped sine wave output format and requires a single 3.3 V supply voltage. It is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm. This component belongs to the IQXT-220-1 series and is designed for surface-mount installation.

Feature Summary

• Temperature compensation ensures high frequency stability of 0.28 ppm across operating conditions.
• Compact 4-SMD no-lead package facilitates space-constrained surface-mount designs.
• Clipped sine wave output format provides compatibility with various receiver inputs.

Applications

• Wireless communication modules requiring precise clocking
• Portable electronic devices with limited board space
• Industrial control systems needing stable timing references

Procurement Notes

Verify the specific orderable part number against the manufacturer's current catalog, as suffixes may indicate variations in packaging or tolerance. Confirm that the 3.3 V supply requirement aligns with the target system's power rails. Ensure the clipped sine wave output is compatible with the receiving circuit's input impedance and voltage levels before finalizing procurement.

Selection Notes

Select this component when a balance of high stability (0.28 ppm) and small footprint is required. The 3.2mm x 2.5mm package is suitable for dense PCB layouts. Consider the clipped sine wave output if the downstream circuitry does not require a square wave. Verify that the 19.2 MHz frequency matches the system's clock requirements and that the 3.3 V supply is available.

Part Context

This TCXO is part of the IQXT-220-1 series from IQD Frequency Products, which specializes in miniature oscillators. The series targets applications demanding low power consumption and high performance in small packages. The LFTCXO075796 specifically addresses needs for stable timing in portable and industrial electronics where size and accuracy are critical constraints.

Replacement Considerations

Check for direct substitutes within the IQXT-220-1 series that offer identical pinout and electrical characteristics. Verify that any replacement maintains the 0.28 ppm stability and 3.3 V supply requirement. Ensure the alternative component supports the same clipped sine wave output format and 4-SMD package dimensions.
