LFSPXO084271

Overview

The LFSPXO084271 is a standard crystal oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 156.25 MHz and requires a supply voltage of 3.3 V. The device features an LVDS output format, suitable for high-speed digital interfaces. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount assembly. This component provides stable clock signals for data transmission applications requiring precise timing synchronization.

Feature Summary

• Generates a precise 156.25 MHz clock signal using standard XO technology.
• Utilizes Low-Voltage Differential Signaling (LVDS) output for noise immunity.
• Operates on a single 3.3 V power supply rail.
• Features a leadless surface-mount package for automated PCB assembly.

Applications

• High-speed serial data communication links
• Network infrastructure equipment
• Telecommunications base stations
• Server backplane clock distribution

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the LVDS output compatibility matches the receiving circuit's input specifications. Ensure the 3.3 V supply voltage aligns with your power management architecture. Check for any specific automotive or industrial qualification needs if applicable to your deployment environment.

Selection Notes

Select this model when a stable 156.25 MHz reference is required for gigabit Ethernet or similar high-bandwidth protocols. The LVDS output is preferred over CMOS for reducing electromagnetic interference in dense layouts. Consider the 4-SMD footprint constraints during mechanical design. Evaluate phase noise specifications if jitter performance is critical for your signal integrity requirements.
