LFTVXO079053

Overview

The LFTVXO079053 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 26 MHz with a frequency stability of ±0.5 ppm. The device requires a supply voltage of 1.8 V and features a clipped sine wave output format. It is designed for surface mount installation in a compact 4-SMD, no lead package measuring 2 mm in length, 1.6 mm in width, and 0.7 mm in height. The component supports an operating temperature range from -30°C to +85°C and utilizes a load capacitance of 10 pF.

Feature Summary

• Integrates voltage-controlled tuning capability within a temperature-compensated crystal oscillator architecture for precise frequency adjustment.
• Delivers high frequency stability of ±0.5 ppm across the specified industrial temperature range.
• Operates on a low 1.8 V power supply, suitable for portable and battery-powered electronic systems.

Applications

• Mobile communication devices requiring stable clock signals
• Wireless data transmission modules
• Portable electronic equipment with space constraints

Procurement Notes

Verify the specific part number suffix against official IQD documentation to confirm exact frequency and tolerance specifications. Ensure compatibility with the target PCB footprint and soldering profile for the 4-SMD package. Confirm that the 1.8 V supply voltage aligns with the system design requirements before procurement.

Selection Notes

Select this component when a small form factor VCTCXO is required for applications needing both temperature compensation and voltage control. The 26 MHz frequency and ±0.5 ppm stability make it suitable for precision timing needs. Consider the 1.8 V supply constraint and clipped sine wave output interface during circuit design.

Part Context

This component belongs to the IQXT-205-2-18 series of VCTCXOs from IQD Frequency Products. It shares the same physical dimensions and basic electrical characteristics as other models in the series, differing primarily in nominal frequency and specific tuning parameters. The series is designed for high-volume surface mount assembly.

Replacement Considerations

Direct substitutes within the same IQD series include LFTVXO079052 and LFTVXO079054, which share identical package dimensions and electrical profiles but operate at different frequencies (20 MHz and 38.4 MHz respectively). Cross-manufacturer replacements require careful verification of pinout, voltage, and stability specifications.
