LFSPXO084278

Overview

The LFSPXO084278 is a standard clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 125 MHz and utilizes an LVPECL output interface. The device is powered by a 2.5 V supply voltage and is housed in a compact 4-SMD, No Lead surface-mount package. 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
• Operates with a 2.5 V power supply for low-voltage compatibility
• Utilizes a compact surface-mount package for efficient PCB integration

Applications

• High-speed serial communication interfaces

• Test and measurement equipment

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the LVPECL output voltage levels are compatible with the receiving logic inputs. Ensure the 2.5 V supply rail meets the current consumption specifications outlined in the official datasheet to maintain signal integrity.

Selection Notes

Select this model when LVPECL outputs are required for 125 MHz applications. Consider the 2.5 V supply constraint and the 4-SMD package dimensions during layout. Evaluate phase noise and jitter specifications if the application demands strict timing accuracy beyond standard performance levels.

Part Context

This part belongs to the LFSPXO series of standard oscillators from IQD Frequency Products. The series offers various frequencies and output types. The LFSPXO084278 specifically targets high-frequency applications using LVPECL technology, distinguishing it from HCMOS or CML variants within the broader product line.

Replacement Considerations
