NSC5391B-125M

Overview

The NSC5391B-125M is a standard frequency crystal oscillator manufactured by NDK. It operates at a nominal frequency of 125 MHz and utilizes LVDS output signaling for high-speed digital applications. The device functions with a supply voltage of 3.3V and includes a standby feature for power-down control. It is housed in a compact 6-SMD, No Lead package designed for surface mount technology.

Feature Summary

• Supports LVDS output interface for reliable high-frequency signal transmission
• Integrates standby functionality to enable power-down mode management
• Operates on a single 3.3V power supply rail

Applications

• High-speed data communication interfaces requiring precise clocking
• Digital signal processing systems needing stable timing references
• Network equipment utilizing LVDS-compatible clock distribution

Procurement Notes

Verify the specific output load requirements and drive level specifications against the target circuit design before procurement. Confirm that the LVDS output compatibility matches the receiving component's input standards. Ensure the 3.3V supply voltage aligns with the system power architecture. Check for any specific thermal management requirements associated with the 6-SMD package during operation.

Selection Notes

Select this component when a 125 MHz clock source with LVDS outputs is required. Consider the 3.3V operating voltage constraint for power budgeting. Evaluate the physical dimensions of the 6-SMD package against available PCB real estate. Compare performance metrics such as phase noise and jitter against application requirements relative to alternative oscillator types.

Part Context

This part belongs to NDK's series of surface-mount crystal oscillators. It provides a fixed frequency solution compared to programmable alternatives. The 6-SMD form factor distinguishes it from larger through-hole or different SMD packages. It serves as a direct replacement for legacy components requiring identical electrical characteristics.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Verify pinout compatibility and electrical parameters if considering cross-brand alternatives. Ensure the replacement supports the same LVDS output type and 3.3V supply requirement.
