LFTCXO085780

Overview

The LFTCXO085780 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 38.88 MHz with a high stability of 0.28 ppm. The device supports a supply voltage range from 3.135 V to 5.5 V and features HCMOS output format. It includes tri-state control and an enable/disable function for power management. The component is RoHS compliant, lead-free, and designed for surface mount installation.

Feature Summary

• High frequency stability of 0.28 ppm
• HCMOS output interface
• Tri-state and enable/disable functionality

Applications

• Precision clock generation in communication systems
• Data acquisition equipment requiring stable timing references
• Industrial control systems with strict frequency tolerance requirements

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the HCMOS output voltage levels are compatible with your downstream logic circuits. Ensure the supply voltage remains within the specified minimum and maximum limits during operation to maintain the stated 0.28 ppm stability. Check for any recent product change notifications regarding package or material updates.

Selection Notes

Select this component when a fixed frequency of 38.88 MHz is required with exceptional short-term and long-term stability. It is suitable for applications where low phase noise and high accuracy are critical. Consider the surface mount package for automated assembly processes. Evaluate the power consumption relative to other TCXO options if battery life is a constraint.

Part Context

This part belongs to the LFTCXO series from IQD Frequency Products, which focuses on high-performance temperature-compensated oscillators. The series is known for combining quartz crystal technology with ASIC-based compensation to achieve superior stability across varying temperatures. This specific model targets markets demanding reliable timing sources in compact form factors.

Replacement Considerations

Direct substitutes must match the 38.88 MHz frequency, 0.28 ppm stability, and HCMOS output. Verify pinout compatibility and thermal characteristics. Consult manufacturer documentation for approved alternate part numbers within the same family or from qualified second-source vendors.
