LFSPXO083345

Overview

The LFSPXO083345 is a standard clock oscillator manufactured by IQD Frequency Products, belonging to the LVPECL series. It operates at a nominal frequency of 125 MHz and utilizes an LVPECL output format. The device is housed in a compact 6-SMD, No Lead package and supports a supply voltage range of 2.7V to 3.63V. Key functional features include an enable/disable control pin for power management. This component is designed for high-speed digital applications requiring precise timing signals.

Feature Summary

• Provides stable LVPECL output signals for high-speed data transmission
• Integrates enable/disable functionality for efficient power management
• Utilizes a surface-mount package suitable for space-constrained designs

Applications

• High-speed networking equipment
• Optical transceiver modules
• Data communication systems

Procurement Notes

Verify the specific operating temperature range and frequency stability requirements against the official datasheet before procurement. Confirm that the 6-SMD package dimensions align with the PCB footprint design. Ensure the supply voltage matches the system's available rail within the specified 2.7V to 3.63V range. Check for any recent part number revisions or alternate packaging options such as tape and reel availability from authorized distributors.

Selection Notes

Select this oscillator when LVPECL signaling is required for noise immunity and high-speed performance. Consider the enable/disable feature if dynamic power saving is necessary. Evaluate the 125 MHz frequency against system clock requirements. Compare physical size constraints with alternative packages if board real estate is limited. Verify compatibility with existing logic levels and termination requirements for LVPECL interfaces.

Part Context

This component is part of IQD Frequency Products' extensive portfolio of quartz crystal parts and oscillators. The LVPECL series is specifically engineered for demanding applications like 5G and Ethernet. IQD provides various output formats including CMOS and HCMOS, but this model focuses on low jitter and low phase noise characteristics typical of LVPECL devices for robust signal integrity.

Replacement Considerations

Direct substitutes must match the 125 MHz frequency, LVPECL output, and 6-SMD package. Verify equivalent electrical specifications such as supply voltage and stability. Consult manufacturer cross-reference guides for officially confirmed alternative part numbers.
