LFTCXO085772

Overview

The LFTCXO085772 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 19.2 MHz with an HCMOS output format. The device is designed for surface mount applications, utilizing a compact 4-SMD, No Lead package. It functions within a supply voltage range of 3.135 V to 3.465 V, typically centered at 3.3 V. The unit supports an extended industrial operating temperature range from -40°C to +85°C, ensuring stable performance in demanding environments.

Feature Summary

• Integrated temperature compensation circuitry maintains frequency stability across the specified operating temperature range.
• HCMOS output interface provides standard logic level compatibility for digital clocking applications.
• Compact surface-mount footprint facilitates automated assembly and space-constrained PCB layouts.

Applications

• Industrial control systems requiring precise timing references
• Telecommunications equipment needing stable clock signals
• Automotive electronics compliant with harsh environmental standards

Procurement Notes

Verify that the specific order quantity meets the manufacturer's minimum packaging requirements before finalizing procurement. Confirm that the requested delivery timeline aligns with current production schedules to avoid project delays. Ensure that the receiving facility has appropriate electrostatic discharge protection measures in place. Review the latest datasheet revision to confirm compliance with current RoHS directives and material declarations prior to component acceptance.

Selection Notes

Select this component when a 19.2 MHz reference signal is required with high thermal stability. The HCMOS output is suitable for direct interfacing with standard logic families without additional buffering. Consider the 4-pin SMD package dimensions against available board real estate. Evaluate the 3.3V supply requirement against the system power architecture to ensure efficient voltage regulation and low noise performance.

Part Context

This TCXO belongs to IQD Frequency Products' LF series, which focuses on miniature surface-mount oscillators. The series utilizes advanced quartz cutting and compensation techniques to achieve superior stability compared to standard crystal oscillators. It complements IQD's broader portfolio of resonators and other oscillator types used in global communication and computing infrastructure.

Replacement Considerations

Cross-reference with other 19.2 MHz TCXOs offering HCMOS outputs and similar 3.3V operation. Verify pinout compatibility and physical package dimensions to ensure mechanical fit. Check if alternative suppliers offer equivalent frequency stability and aging specifications for the same temperature range.
