NSC5004A-25M

Overview

The NSC5004A-25M is a standard CMOS crystal oscillator manufactured by NDK. It operates at a nominal frequency of 25 MHz and supports a supply voltage of 1.8V. The device features a standby (power-down) function for energy management. It utilizes a 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm. This component is designed for surface-mount assembly in compact electronic circuits requiring precise clock signals.

Feature Summary

• Integrates a standby mode to reduce power consumption during idle periods
• Delivers standard CMOS output signals for digital logic compatibility
• Utilizes a low-profile surface-mount package for space-constrained designs

Applications

• Portable consumer electronics requiring low-power clock sources
• Embedded systems utilizing 1.8V logic families
• Mobile communication devices needing precise timing references

Procurement Notes

Verify the specific supply voltage requirement matches the target circuit design, as this variant is specified for 1.8V operation. Confirm that the PCB footprint aligns with the 4-SMD No Lead package dimensions. Ensure the application logic levels are compatible with the CMOS output characteristics provided by the manufacturer datasheet.

Selection Notes

Select this component when a 25 MHz clock signal is required within a 1.8V powered system. Consider the standby feature if power efficiency is critical. Compare against other NDK series like the NSC5004D if a 3.3V supply is necessary instead. Evaluate the package size constraints against available board space.

Part Context

This part belongs to the NSC5004 series of surface-mount oscillators from NDK. It shares the same physical footprint and functional architecture with variants such as the NSC5004D-25M, which differs primarily in its supported supply voltage range. The series is characterized by compact packaging and integrated power management capabilities.
