NSC5021D-40M

Overview

The NSC5021D-40M is a standard CMOS oscillator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a frequency of 40 MHz with a surface-mount package type of 4-SMD, No Lead. The device supports a supply voltage of 3.3V and includes a standby or power-down function for energy management. This component is classified under oscillators and is designed for applications requiring precise timing signals in electronic circuits.

Feature Summary

• Integrated standby and power-down functionality to manage power consumption during idle states
• CMOS output signal suitable for digital logic interfacing
• Surface-mount construction for automated assembly processes

Applications

• General-purpose digital circuit timing
• Microcontroller clock sources
• Communication interface synchronization

Procurement Notes

Verify the specific operating voltage requirements against the target system design to ensure compatibility with the 3.3V specification. Confirm that the 4-SMD package dimensions align with the PCB footprint constraints. Check for any required pull-up or pull-down resistor configurations as specified in the official datasheet to guarantee stable operation and signal integrity.

Selection Notes

Select this component when a low-power, surface-mount oscillator with standby capability is required. The 40 MHz frequency and CMOS output make it suitable for general digital applications. Ensure the design accounts for the specific load conditions and thermal environment, as performance may vary with temperature. Compare against other NDK series if different package sizes or frequencies are needed.

Part Context

This part belongs to the oscillator category within NDK's portfolio. It is distinct from crystal units like the CS14526-32M, as it provides a complete oscillating circuit rather than just a resonant element. The 4-SMD form factor is common for compact consumer electronics and industrial control boards where space efficiency is critical.

Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 3.3V supply, CMOS output, and 4-SMD package. Verify pinout compatibility before replacement.
