NSC5318E-49.58M

Overview

The NSC5318E-49.58M is a temperature-compensated crystal oscillator (TCXO) manufactured by NDK. It operates at a nominal frequency of 49.58 MHz with a high frequency stability of ±500 ppb. The device utilizes a clipped sine wave output and requires a supply voltage of 1.8V. It is housed in a compact 4-SMD, no-lead package designed for surface mount applications. The component supports an operating temperature range from -30°C to 85°C, ensuring reliable performance across various industrial environments.

Feature Summary

• Temperature compensation mechanism ensures high frequency stability of ±500 ppb
• Compact 4-SMD surface-mount package design for space-constrained applications
• Low voltage operation at 1.8V supply
• Clipped sine wave output signal format

Applications

• Precision timing circuits requiring stable clock sources
• Industrial control systems operating in wide temperature ranges
• Communication equipment utilizing 49.58 MHz frequencies
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific output waveform requirement, as this component provides a clipped sine wave rather than a standard square or CMOS signal. Ensure the design accommodates the 1.8V supply voltage constraint. Confirm that the ±500 ppb stability meets the system's jitter and phase noise specifications. Check for any specific layout guidelines regarding the 4-SMD package thermal management during soldering processes.

Selection Notes

Select this component when high frequency stability is critical over a wide temperature range (-30°C to 85°C). It is suitable for applications where size constraints favor a 4-SMD footprint. Consider the clipped sine wave output compatibility with downstream circuitry. Compare against standard crystals if temperature compensation is not required, or against other TCXOs if different voltage or stability levels are needed.
