NSC5118S-19.2M

Overview

The NSC5118S-19.2M is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by NDK. It operates at a nominal frequency of 19.2 MHz with a stability of ±4.6 ppm and supports CMOS output levels. The device functions on a 3.3 V supply voltage and includes an enable/disable control feature. It is housed in a compact 10-SMD, No Lead package and is rated for an operating temperature range of -40°C to 105°C.

Feature Summary

• Integrates temperature compensation and voltage control within a single surface-mount component
• Provides precise frequency stability suitable for high-performance communication systems
• Features CMOS logic output compatible with standard digital interfaces
• Includes hardware enable and disable functionality for power management

Applications

• Wireless communication modules requiring stable clock sources
• Portable electronic devices with strict size constraints
• Automotive electronics systems operating in extreme temperatures
• Industrial control equipment needing reliable timing signals

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and electrical specifications. Confirm that the required frequency tolerance and load capacitance match the target circuit design. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the selected package variant matches the PCB footprint requirements.

Selection Notes

Select this component when a small form factor oscillator with integrated temperature compensation is required. The CMOS output level simplifies interface design compared to current-source outputs. Consider the ±4.6 ppm stability for applications demanding higher precision than standard TCXOs. Evaluate the 3.3 V supply requirement against the system's available voltage rails.

Part Context

This part belongs to NDK's NSC series of voltage-controlled temperature-compensated crystal oscillators. These components are designed to replace discrete oscillator designs, offering superior performance in a reduced footprint. The series utilizes synthetic quartz technology to achieve high reliability and stability across wide temperature ranges.

Replacement Considerations

Consult the official NDK replacement guide for direct substitutes. Verify compatibility regarding pin configuration, supply voltage, and output type before substitution.
