NSC5021A-20M

Overview

The NSC5021A-20M is a standard CMOS oscillator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a frequency of 20 MHz with a supply voltage of 1.8V and features a standby function for power management. The device utilizes a 4-SMD, No Lead package suitable for surface mount applications. Frequency stability is rated at ±50ppm, and it supports an operating temperature range from -40°C to 105°C.

Feature Summary

• Integrated standby mode for power down capability
• CMOS output signal compatibility
• Wide industrial temperature range operation

Applications

• Portable electronic devices requiring low power consumption
• Industrial control systems operating in extreme temperatures
• Communication equipment utilizing standard clock signals

Procurement Notes

Verify the specific supply voltage requirement of 1.8V against your system design before procurement. Confirm that the ±50ppm frequency stability meets your application's timing accuracy needs. Ensure the 4-SMD package footprint aligns with your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a compact 20 MHz clock source with low voltage operation is required. The standby feature makes it suitable for battery-powered applications where power efficiency is critical. Consider the wide temperature range if the environment exceeds standard commercial limits. Compare against other NDK series like RNA or NX if different package sizes or stability levels are needed.

Part Context

This oscillator belongs to NDK's line of surface-mount crystal oscillators designed for high reliability. The NSC5021A series specifically targets applications needing small footprints and low power. As a standard XO, it provides a fixed frequency output without external tuning requirements, simplifying circuit design compared to VCXOs or TCXOs.
