NSC5021D-48M

Overview

The NSC5021D-48M is a CMOS crystal oscillator manufactured by NDK. It operates at a nominal frequency of 48.0000 MHz and utilizes a standard CMOS output interface. The device supports a supply voltage range of 3.3V and features a standby function for power-down control. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.0mm x 3.2mm. The component is designed for surface-mount installation and offers high stability suitable for digital clock signal generation.

Feature Summary

• Integrated CMOS output driver for direct logic interfacing
• Built-in standby mode to reduce power consumption during idle periods
• Compact 4-SMD surface-mount footprint for space-constrained designs

Applications

• Digital system clock generation
• Microprocessor timing references
• Communication equipment synchronization

Procurement Notes

Verify the specific output load requirements and supply voltage tolerance against the target circuit design before procurement. Confirm that the selected package variant matches the PCB land pattern specifications. Ensure the operating temperature range aligns with the environmental conditions of the final application to maintain frequency stability.

Selection Notes

Select this component when a precise 48 MHz reference is required for CMOS-based digital circuits. Consider the standby feature if power management is critical. Evaluate the thermal performance within the -40°C to +85°C range. Compare against alternative oscillators if tighter frequency stability or different form factors are needed for the specific board layout constraints.

Part Context

This part belongs to NDK's NSC series of standard CMOS oscillators. It provides a reliable clock source for embedded systems requiring a fixed frequency. The series is characterized by low phase noise and stable operation across industrial temperature ranges, making it suitable for general-purpose electronic applications.

Replacement Considerations

Direct substitutes must match the 48 MHz frequency, CMOS output type, 3.3V supply, and 4-SMD package dimensions. Verify pin compatibility and electrical characteristics such as rise/fall times and drive strength.
