LFTVXO076347

Overview

The LFTVXO076347 is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 19.2 MHz with a clipped sine wave output format. The device requires a supply voltage of 3.3 V and features a maximum current consumption of 3.5 mA. It offers high frequency stability of ±0.25 ppm across the operating temperature range of -5°C to +85°C, with a tolerance of ±1 ppm. The component is housed in a compact 6-SMD, No Lead package measuring 7.00 mm x 5.00 mm x 2.00 mm.

Feature Summary

• Integrates temperature compensation circuitry to maintain signal stability across varying thermal conditions.
• Provides voltage-controlled tuning capability for precise frequency adjustment within specified limits.
• Delivers a clipped sine wave output suitable for RF and communication interface applications.

Applications

• Wireless communication systems requiring stable clock sources
• GPS receiver modules needing precise timing references
• Industrial control equipment operating in variable temperatures

Procurement Notes

Verify that the specific part number matches the required frequency and stability specifications before integration. Confirm that the 3.3 V supply voltage aligns with the system power architecture. Ensure the 6-SMD package dimensions fit the designated PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when both temperature compensation and voltage control are necessary for frequency accuracy. The 19.2 MHz frequency is standard for certain digital interfaces. Consider the clipped sine wave output compatibility with downstream logic or RF stages. Evaluate the -5°C to +85°C range against the operational environment requirements.

Part Context

This oscillator belongs to the IQXT-316-5 series from IQD Frequency Products. It is designed for applications demanding high stability without the size constraints of OCXOs.
