LFTVXO076349

Overview

The LFTVXO076349 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) from the IQXT-316 series by IQD Frequency Products. It operates at a nominal frequency of 30.72 MHz with a frequency stability of ±0.25 ppm. The device utilizes a clipped sine wave output format and requires a supply voltage ranging from 500 mV to 7 V, typically powered at 3.3 V. It features a maximum supply current of 4.5 mA and a load capacitance of 30 pF. The component is housed in a 6-SMD, No Lead package measuring 7 mm x 5 mm x 2.0 mm. It supports surface mount installation and functions within an operating temperature range of -5°C to +85°C.

Feature Summary

• Integrated temperature compensation for high frequency stability
• Voltage-controlled tuning capability via external control input
• Clipped sine wave output suitable for low-noise applications

Applications

• Wireless communication systems requiring precise clocking
• Test and measurement equipment needing stable reference frequencies
• Industrial control systems operating in varying thermal environments

Procurement Notes

Verify the specific ordering suffix and revision status when sourcing this component, as manufacturer part number revisions may occur without functional changes. Confirm that the required supply voltage range aligns with your system design, noting the minimum start-up voltage of 500 mV. Ensure compatibility with the 30.72 MHz frequency and clipped sine wave output format for your target application circuitry before finalizing procurement.

Selection Notes

Select this VCTCXO when a balance of high stability (±0.25 ppm) and voltage control is required in a compact SMD footprint. Consider the 7mm x 5mm package size against board space constraints. Evaluate the 4.5 mA current draw against power budget requirements. Verify that the -5°C to +85°C operating range meets environmental specifications. Compare against other IQXT-316 variants if different frequencies or output formats are needed.

Part Context

This component belongs to the IQD Frequency Products VCTCXO family, designed for applications demanding superior frequency accuracy over temperature variations. The IQXT-316 series specifically targets compact designs requiring voltage-controlled tuning. IQD Frequency Products, now part of Wurth Elektronik, provides these oscillators for global markets in automotive, industrial, and communications sectors.

Replacement Considerations

Check for direct cross-references within the IQXT-316 series for alternative frequencies. Verify pinout compatibility if substituting with similar VCTCXOs from other manufacturers. Ensure the replacement maintains the ±0.25 ppm stability and clipped sine wave output characteristics.
