LFSPXO083319

Overview

The LFSPXO083319 is a 125 MHz standard clock oscillator from the IQXO-618-33 series, manufactured by IQD Frequency Products. It features an LVDS differential output and operates on a 3.3 V supply voltage. The device supports a standby (power-down) function to reduce power consumption during idle periods. It is housed in a compact 6-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm. The component is designed for industrial applications, ensuring reliable performance within specified operating temperature ranges.

Feature Summary

• LVDS differential output interface for high-speed signal integrity
• Integrated standby mode for power management optimization
• Hermetically sealed ceramic and metal construction for environmental robustness

Applications

• Industrial communication equipment requiring precise timing
• High-speed data transmission systems
• FPGA and PHY chip clock sources

Procurement Notes

Verify the specific frequency stability and aging rate requirements against the official datasheet before procurement. Confirm that the LVDS output voltage levels are compatible with the receiving circuitry. Ensure the selected variant meets the required operating temperature range for the intended application environment. Check for any specific ordering suffixes that may affect pinout or functionality.

Selection Notes

Select this oscillator when a low-jitter, high-frequency clock source is needed for digital circuits. The LVDS output is suitable for long-distance traces or noisy environments. Consider the power-down feature if energy efficiency is critical. Compare the package size constraints with available PCB space. Evaluate the thermal performance under continuous operation conditions.

Part Context

This part belongs to the IQXO-618-33 series of hermetically sealed oscillators. These components are designed for demanding industrial and automotive-grade applications where reliability is paramount. The series offers various frequencies and output types, with the LFSPXO083319 specifically providing a 125 MHz LVDS signal. The hermetic sealing protects the internal MEMS or crystal element from moisture and contaminants.

Replacement Considerations

Direct replacements must match the 125 MHz frequency, LVDS output type, and 3.3 V supply voltage. Verify pin compatibility and package dimensions (3.2x2.5mm SMD). Check if alternative manufacturers offer equivalent hermetically sealed packages. Ensure the replacement supports the same standby functionality if required.
