NSC5021A-25M

Overview

The NSC5021A-25M is a standard CMOS crystal oscillator manufactured by NDK. It operates at a frequency of 25 MHz with a supply voltage of 1.8V. The device features a standby (power down) function and is housed in a 4-SMD, No Lead package.

Feature Summary

• CMOS output signal
• Standby mode support
• Low profile surface mount design

Applications

• Portable electronic devices
• Communication equipment
• Embedded systems requiring low power consumption

Procurement Notes

Verify the specific load capacitance and stability requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Ensure the 4-SMD footprint matches your PCB layout constraints to avoid assembly issues.

Selection Notes

Select this component when a precise 25 MHz clock source is required for digital logic interfacing. The integrated standby feature makes it suitable for battery-operated applications where power conservation during idle states is critical. Verify compatibility with the target microcontroller or FPGA clock inputs.

Part Context

This part belongs to NDK's NX series of surface mount crystal oscillators. These components are designed to replace through-hole crystals by providing a complete, ready-to-use clock solution. The series emphasizes miniaturization and reliability for modern consumer electronics.

Replacement Considerations

Direct substitutes may include other 25MHz 1.8V CMOS oscillators from NDK such as the NZ2016SH series if pinout and size compatibility are verified. Cross-reference with other manufacturers' 3225-sized 25MHz XO parts only after confirming electrical parameter equivalence.
