LFTVXO085768

Overview

The LFTVXO085768 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 38.88 MHz with an output format of HCMOS. The device supports amplitude control and functions within a supply voltage range of 3.135 V to 3.465 V. It exhibits a frequency stability of ±0.28 ppm and a total frequency tolerance of ±1.00 ppm. The component is designed for operation across an extended temperature range from -40°C to +105°C. It utilizes a compact 4-SMD, No Lead package measuring 7.00 mm in length, 5.00 mm in width, and 2.00 mm in height.

Procurement Notes

Verify the specific ordering suffix and revision level against the official IQD datasheet to ensure compatibility with required frequency stability and packaging specifications. Confirm that the supplier provides traceable documentation matching the manufacturer's part identification. Cross-reference the RoHS compliance status and lead-free characteristics as stated in the product specifications before finalizing procurement orders.

Selection Notes

Select this component when a stable 38.88 MHz reference is required with voltage tuning capabilities. Ensure the application environment stays within the specified -40°C to +105°C operational limits. Verify that the HCMOS output swing matches the input requirements of the downstream circuitry. Consider the 4-SMD package dimensions for PCB layout constraints and thermal management requirements during the design phase.

Part Context

This oscillator belongs to the IQXT series from IQD Frequency Products, a division of Wurth Elektronik. The series specializes in high-performance crystal oscillators designed for demanding applications. IQD leverages extensive experience in frequency control to provide components that meet rigorous industry standards for stability and reliability across various sectors including automotive and industrial markets.

Replacement Considerations

Direct substitutes must match the 38.88 MHz frequency, VCTCXO type, HCMOS output, and ±0.28 ppm stability. Verify pinout compatibility for the 4-SMD No Lead package. Check if alternative models offer identical voltage control ranges and temperature stability profiles to ensure seamless integration without circuit redesign.
