NSC5021D-20M

Overview

The NSC5021D-20M is a standard CMOS crystal oscillator manufactured by NDK. It operates at a nominal frequency of 20 MHz with a surface-mount 4-SMD, no-lead package measuring 3.2mm x 2.5mm and a maximum height of 0.80mm. The device supports a supply voltage of 3.3V and includes a standby power-down function. It is designed for base resonator applications within electronic circuits requiring precise timing signals.

Feature Summary

• Integrates a CMOS output stage for direct logic interfacing
• Features a low-profile surface-mount package suitable for space-constrained designs
• Includes a standby mode to reduce power consumption during inactivity

Applications

• Digital signal processing systems
• Communication equipment clock sources
• Microcontroller timing references

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 3.3V supply specification aligns with the target circuit design. Ensure the 4-SMD footprint dimensions match the PCB layout constraints. Check for any recent product change notices regarding manufacturing updates.

Selection Notes

Select this component when a standard CMOS output is required for a 20 MHz application. Consider the 3.3V supply voltage and standby capability for power management needs. Evaluate the 4-SMD package size against available board space. Compare performance metrics with alternative oscillators if stricter stability or lower noise specifications are necessary for the specific application.

Part Context

This part belongs to the NSC5021D series of surface-mount crystal oscillators from NDK. The series provides standardized timing solutions with CMOS outputs. The 20 MHz variant offers a balance of speed and power efficiency. It is distinct from NDK's passive crystals and voltage-controlled oscillator variants.

Replacement Considerations

ECS-130-8-30B-CKM is listed as a similar replacement option for related discontinued parts, though direct substitution requires verification of electrical parameters.
