LFTVXO075806

Overview

The LFTVXO075806 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) 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 supply voltage of 3.3 V. It is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm. The component supports an operating temperature range from -40°C to +85°C and belongs to the IQXT-220-2 series.

Feature Summary

• Integrates temperature compensation circuitry for high frequency stability across wide thermal ranges
• Provides voltage control capability for precise frequency tuning applications
• Delivers clipped sine wave output suitable for RF signal generation
• Utilizes surface mount packaging for automated assembly integration

Applications

• Wireless communication base stations
• RF signal processing systems
• Test and measurement equipment
• Industrial control modules requiring stable clock references

Procurement Notes

Verify the specific suffix codes against the manufacturer's official documentation to ensure correct output waveform and tolerance specifications. Confirm that the required supply voltage aligns with system power rails before integration. Check current datasheets for any recent product change notifications or pinout revisions. Ensure compatibility with existing PCB footprint dimensions and soldering profiles.

Selection Notes

Select this component when a stable 19.2 MHz reference with voltage control is required in space-constrained designs. The clipped sine wave output is appropriate for driving RF stages directly. Consider the ±0.28 ppm stability requirement against system jitter budgets. Evaluate the 3.3 V supply constraint against available power management solutions. Verify the operating temperature range meets environmental conditions.

Part Context

This oscillator belongs to the IQXT-220-2 series from IQD Frequency Products, designed for applications demanding high stability in small form factors. The VCTCXO architecture combines crystal resonance with active temperature compensation and voltage control loops. This specific model targets markets requiring reliable clock sources for data transmission and synchronization tasks.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify equivalent frequency, stability, package size, and output waveform characteristics. Ensure replacement parts meet the same electrical and thermal specifications.
