NSC5342B-125M

Overview

The NSC5342B-125M is a 125 MHz crystal oscillator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates in the standard XO configuration with LVPECL output levels and supports a 3.3V supply voltage. The device features a standby function for power-down control. It is housed in a compact 6-SMD, no-lead package designed for surface-mount assembly.

Feature Summary

• LVPECL output interface for high-speed digital signaling
• Integrated standby mode enabling power-down capability
• Surface-mount construction in a small form factor

Applications

• High-speed serial communication interfaces
• Data transmission equipment requiring precise clocking
• Network infrastructure components

Procurement Notes

Verify that the target circuit design accommodates LVPECL logic levels and 3.3V operation. Confirm mechanical compatibility with the 6-SMD footprint during PCB layout. Ensure thermal management aligns with the component's surface-mount specifications to maintain performance stability under load.

Selection Notes

Select this component when LVPECL outputs and standby functionality are required at 125 MHz. Compare against other oscillators if lower power consumption or different output formats like HCMOS are needed. Evaluate package size constraints against alternative SMD options from the manufacturer.

Part Context
