LFTVXO063792BULK

Overview

The LFTVXO063792BULK is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a clipped sine wave output format. The device requires a 3.3V supply voltage and draws a maximum current of 10mA. It features a frequency stability of ±140ppb and functions within an operating temperature range of -40°C to +85°C. The component utilizes a crystal as its basic resonator and is housed in an 8-SMD module package measuring 5.00mm x 3.20mm with a maximum height of 2.20mm.

Feature Summary

• Integrated temperature compensation for enhanced frequency stability across wide thermal ranges
• Voltage-controlled operation allowing precise frequency tuning via control voltage input
• Clipped sine wave output suitable for driving subsequent logic or mixing stages
• Surface-mount construction designed for automated assembly processes

Applications

• Wireless communication systems requiring stable carrier frequencies
• Test and measurement equipment needing low phase noise sources
• Industrial control systems operating in variable environmental temperatures
• Navigation and positioning modules demanding high frequency accuracy

Procurement Notes

Verify the specific suffix and packaging configuration against official IQD documentation before ordering, as bulk packaging variants may differ from tape-and-reel options. Confirm that the required control voltage range and load capacitance match your circuit design specifications. Ensure compatibility with the 3.3V supply rail and check for any RoHS compliance requirements relevant to your region. Cross-reference the exact part number with the manufacturer's latest datasheet to confirm availability and lead times through authorized distributors.

Selection Notes

Select this component when a balance of high stability and compact size is required for 20 MHz applications. Consider the ±140ppb stability metric against your system's jitter tolerance requirements. Evaluate the 8-SMD footprint constraints against your PCB layout capabilities. Compare power consumption figures with other oscillators if battery life is a critical design factor. Ensure the operating temperature range covers the full environmental spectrum of the intended deployment scenario.

Part Context

This oscillator belongs to the IQXT-210-4 series from IQD Frequency Products, which specializes in extended-temperature VC/TCXOs. The brand is a subsidiary of Wurth Elektronik, known for providing comprehensive frequency control solutions. This series targets applications requiring reliable performance in harsh environments where standard crystals might drift significantly due to temperature fluctuations.

Replacement Considerations

Direct replacements must match the 20 MHz frequency, 3.3V supply, and 8-SMD package dimensions. Verify that substitute VCTCXOs offer comparable ±140ppb stability and clipped sine wave outputs. Check pinout compatibility to avoid redesigning the control voltage interface. Ensure the replacement supports the same -40°C to +85°C operating range.
