NSC5021A-40M

Overview

The NSC5021A-40M is a CMOS crystal oscillator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a frequency of 40 MHz and utilizes a standard CMOS output interface. The device supports a 1.8V standby mode for power-down functionality, enhancing energy efficiency in portable applications. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly. The component is currently active and available for procurement through authorized distributors.

Feature Summary

• Integrated CMOS output stage for direct logic interfacing
• Supports 1.8V standby mode to minimize power consumption during idle periods
• Compact 4-SMD no-lead surface mount package design

Applications

• Portable electronic devices requiring low-power clock sources
• Embedded systems utilizing CMOS-compatible logic families
• Communication modules needing stable 40 MHz timing references

Procurement Notes

Verify the specific voltage tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V standby feature aligns with your power management strategy. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any series-specific environmental compliance documentation if required for your region.

Selection Notes

Select this model when a precise 40 MHz reference is needed with minimal power draw. The CMOS output simplifies integration with digital circuits compared to LVDS or HCSL variants. Consider the standby capability if the system frequently enters sleep modes. Evaluate the thermal performance within the 4-SMD package for high-density designs.
