Overview
The LFTCXO085792 is a temperature-compensated crystal oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a frequency stability of +/-0.28 ppm. The device utilizes HCMOS output format and requires a supply voltage of 3.3 V. It is housed in a compact surface-mount package measuring 5 mm x 3.2 mm. This component is designed for applications requiring precise timing signals within a small form factor.
Feature Summary
- Temperature compensation ensures high frequency stability across operating ranges
- HCMOS output format provides standard digital logic compatibility
- Compact surface-mount package design facilitates space-constrained PCB layouts
Applications
- Telecommunications equipment requiring stable clock references
- Portable electronic devices with limited board space
- Industrial control systems needing precise timing synchronization
Procurement Notes
Verify the specific part number against official IQD Frequency Products documentation to confirm electrical characteristics and mechanical dimensions. Ensure that the required frequency stability, output format, and supply voltage align with the system design specifications before procurement. Cross-reference the package type to confirm compatibility with existing assembly processes.
Selection Notes
Select this TCXO when a 20 MHz reference with +/-0.28 ppm stability is required in a 5x3.2mm SMD footprint. Consider the HCMOS output interface for direct logic interfacing. Evaluate the 3.3V supply requirement against available power rails. Compare performance metrics against alternative oscillators if tighter stability or different packaging is needed.
Part Context
This component belongs to the IQD Frequency Products TCXO portfolio, which offers temperature-compensated solutions for various frequency applications. The LFTCXO series typically features low phase noise and high stability, making it suitable for demanding timing environments. IQD leverages advanced quartz technology to deliver reliable performance in compact packages.
Replacement Considerations
Consult official substitution guides from IQD Frequency Products for verified compatible alternatives. Ensure any replacement matches the 20 MHz frequency, +/-0.28 ppm stability, HCMOS output, and 5x3.2mm package dimensions. Verify supply voltage and pinout compatibility to maintain circuit functionality without redesign.
