LFTCXO085793

Overview

The LFTCXO085793 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 38.88 MHz with an HCMOS output format. The device provides high frequency stability of 0.28 ppm and is housed in a compact 5mm x 3.2mm surface-mount package. It functions within a supply voltage range of 3.135 V to 3.465 V, supporting a load capacitance of 15 pF. The component is rated for operation between -40 °C and +105 °C, ensuring reliability in demanding environments.

Feature Summary

• Utilizes Pluto ASIC technology for sub-1ppm performance and extended temperature compensation
• Features low power consumption suitable for mobile applications
• Includes tri-state and enable/disable functionality for system management

Applications

• Mobile communication devices requiring precise timing references
• Industrial systems operating across wide temperature ranges
• Automotive electronics compliant with strict environmental standards

Procurement Notes

Verify the specific order code suffix against the official IQD catalog to confirm pinout configuration and tolerance levels. Ensure the requested variant matches the required operating temperature range and output drive strength. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when high precision timing is critical alongside space constraints. The 5mm x 3.2mm footprint offers a balance between performance and size. Consider the 0.28 ppm stability for applications sensitive to frequency drift. Verify that the HCMOS output interface aligns with the target system's logic voltage levels.

Part Context

This oscillator belongs to the IQD LF series, which leverages Rakon’s Pluto ASIC technology. The series is designed for high stability and low power consumption. It serves as a reliable clock source for digital circuits requiring accurate frequency generation without the complexity of larger oven-controlled oscillators.

Replacement Considerations

Direct substitutes include other TCXOs from the same family with matching 38.88 MHz frequency and 5x3.2mm dimensions. Verify equivalent stability specifications and supply voltage compatibility before swapping components.
