LFTVXO076348

Overview

The LFTVXO076348 is a VCTCXO oscillator from the IQXT-316-6 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of ±250 ppb over the operating temperature range. The device utilizes a clipped sine wave output format and requires a supply voltage between 500 mV and 7 V, typically powered at 3.3 V. It features a maximum supply current of 4.5 mA and is housed in a 6-SMD, no-lead package measuring 7.00 mm x 5.00 mm x 2.00 mm. The component supports surface mount installation and functions within a temperature range of -5°C to +85°C.

Feature Summary

• Provides precise frequency control via voltage-controlled tuning for applications requiring high stability.
• Delivers clipped sine wave output suitable for driving specific logic or RF input stages.
• Operates on a wide supply voltage range from 500 mV to 7 V, accommodating various power architectures.

Applications

• Wireless communication systems requiring stable carrier frequencies
• Test and measurement equipment needing precise timing references
• Industrial control systems utilizing clock synchronization

Procurement Notes

Verify the exact revision status when ordering, as the manufacturer has updated part number revisions for this component. Confirm that the required output format matches the clipped sine wave specification rather than digital logic levels. Ensure the design accommodates the specified 6-SMD no-lead footprint dimensions and thermal requirements for the -5°C to +85°C operating range.

Selection Notes

Select this model when a voltage-controlled oscillator is necessary for frequency adjustment within a narrow tolerance band. The clipped sine wave output distinguishes it from HCMOS or LVDS alternatives. Consider the 4.5 mA maximum current draw for power budgeting. The 7mm x 5mm package size offers a balance between performance and board space compared to larger hermetic packages.

Part Context

This component belongs to the IQXT-316-6 series of voltage-controlled crystal oscillators. It represents a surface-mount solution designed for modern electronics where space constraints and electrical performance are critical. The series provides temperature-compensated stability while allowing for external frequency trimming through the control voltage pin.
