NSC5004A-50M

Overview

The NSC5004A-50M is a standard CMOS oscillator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a frequency of 50 MHz and features a 1.8V standby capability for power-down functionality. The component utilizes a 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm. It is designed for surface mount installation and supports industrial temperature ranges typical for such oscillators.

Feature Summary

• Integrates standard CMOS output interface for digital logic compatibility
• Includes 1.8V standby mode to enable power-down functionality
• Utilizes compact 4-SMD no-lead surface mount packaging

Applications

• Digital clock signal generation in embedded systems
• Timing reference for microprocessors and FPGAs
• Communication equipment requiring stable 50MHz source

Procurement Notes

Verify the specific load capacitance and stability requirements against the system design before ordering. Confirm that the 1.8V standby voltage aligns with the control logic levels used in the target application. Ensure the 4-SMD footprint matches the PCB layout constraints. Check for any specific RoHS compliance documentation if required by the end product regulations.

Selection Notes

Select this component when a precise 50 MHz timing source is required with low-power standby capabilities. The CMOS output makes it suitable for direct interfacing with standard digital logic families. Consider the physical size of the 4-SMD package for space-constrained designs. Evaluate the thermal performance if the device will operate in high-temperature environments.

Part Context

This part belongs to NDK's series of surface-mount crystal oscillators. It provides a fixed frequency output without external tuning components. The 50 MHz frequency is commonly used in data communication and computing applications. The no-lead package offers improved solder joint reliability compared to traditional leaded packages.

Replacement Considerations

Direct substitutes may include other 50 MHz CMOS oscillators from NDK or competitors with identical pinout and electrical specifications. Verify that the replacement maintains the same 1.8V standby feature and package dimensions. Cross-reference the frequency stability and phase noise requirements to ensure functional equivalence.
