LFTVXO079055

Overview

The LFTVXO079055 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 52 MHz with a high frequency stability of ±0.5 ppm. The device is powered by a single 1.8 V supply and features a clipped sine wave output format. It is housed in a compact 4-SMD, No Lead package designed for surface mount installation.

Feature Summary

• Integrated temperature compensation ensures precise frequency stability across the operating range.
• Voltage control capability allows for fine-tuning of the output frequency.
• Compact surface-mount footprint facilitates automated assembly and space-constrained designs.

Applications

• Wireless communication systems requiring stable clock references
• Portable electronic devices with limited power budgets
• Industrial instrumentation needing precise timing signals

Procurement Notes

Verify the specific output load requirements and voltage control sensitivity against your circuit design before procurement. Confirm that the 1.8 V supply rail meets the current consumption specifications during peak operation. Ensure the PCB layout accommodates the 4-SMD no-lead package dimensions to prevent soldering defects. Cross-reference the latest datasheet revision to confirm pinout compatibility with existing schematics.

Selection Notes

Select this component when a balance between low power consumption and high frequency accuracy is required. The 1.8 V supply makes it suitable for battery-operated or low-voltage logic environments. Consider the clipped sine wave output if subsequent stages can handle non-square waveforms, potentially reducing filtering requirements compared to HCMOS outputs.

Part Context

This oscillator belongs to the IQXT-205-2-18 series from IQD Frequency Products, which specializes in miniature surface-mount oscillators. The series is designed for applications demanding tight frequency tolerances in small form factors. IQD is a recognized supplier of frequency control products within the Würth Elektronik eiSos group, serving global markets in communications and industrial sectors.

Replacement Considerations

Direct replacements must match the 52 MHz frequency, ±0.5 ppm stability, 1.8 V supply, and 4-SMD no-lead package. Verify that any substitute part supports clipped sine wave output and compatible voltage control characteristics. Check for equivalent thermal performance and aging rates to ensure system reliability remains unchanged.
