LFTVXO075808

Overview

The LFTVXO075808 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 30.72 MHz with a clipped sine wave output format. The device requires a 3.3V supply voltage and features a frequency stability of ±280ppb. It is housed in a compact 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a maximum seated height of 1.00mm. The oscillator supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated temperature compensation for enhanced frequency stability across varying thermal conditions
• Voltage control capability allows for precise frequency adjustment via external tuning signals
• Compact surface-mount design suitable for space-constrained electronic applications

Applications

• Wireless communication systems requiring stable clock sources
• Portable electronic devices needing low-power oscillators
• Industrial control equipment operating in variable temperature environments

Procurement Notes

Verify the specific output waveform requirement, as this model provides a clipped sine wave rather than digital logic levels. Confirm that the system interface can accommodate analog-style outputs or includes necessary buffering circuitry. Ensure the 3.3V supply rail is stable within the specified operating parameters to maintain the stated frequency stability. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when high frequency stability is critical but full OCXO performance is unnecessary. The VCTCXO architecture offers a balance between power consumption and precision. Consider the clipped sine output format against alternatives offering HCMOS or LVDS if digital interfacing is preferred without additional conversion stages. Evaluate the 4-SMD footprint against available PCB real estate constraints.

Part Context

This part belongs to the IQD Frequency Products oscillator portfolio, which specializes in quartz-based timing solutions. The manufacturer leverages extensive experience in frequency control to provide components for global industries including automotive, medical, and industrial sectors. This specific model represents their surface-mount VCTCXO offerings designed for modern miniaturized electronics.

Replacement Considerations

Cross-reference with other IQD VCTCXO models in the same series for pin-compatible alternatives. Verify that substitute parts match the 30.72 MHz frequency, 3.3V supply, and ±280ppb stability requirements. Ensure the replacement maintains the clipped sine wave output characteristic if direct signal compatibility is needed.
