NSA0345E-26M

Overview

The NSA0345E-26M is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by NDK. It operates at a frequency of 26 MHz and utilizes a clipped sine wave output signal. The device is designed for low-voltage applications, specifically supporting a supply voltage of 1.8V. It is housed in a compact 4-SMD, No Lead surface-mount package, suitable for space-constrained electronic designs requiring stable clock signals.

Feature Summary

• Integrates temperature compensation circuitry to maintain frequency stability across operating conditions.
• Provides a clipped sine wave output signal optimized for digital logic interfaces.
• Supports low-voltage operation with a specified 1.8V supply requirement.

Applications

• Mobile communication devices requiring precise timing references.
• Portable consumer electronics utilizing low-power clock sources.
• Embedded systems needing stable oscillation in compact form factors.

Procurement Notes

Verify component obsolescence status prior to procurement. The NSA0345E-26M is listed as obsolete and no longer in production. Confirm availability through authorized distributors for remaining stock or identify approved replacement components from the manufacturer's current portfolio to ensure long-term supply chain stability.

Selection Notes

Select this component only if legacy compatibility with 1.8V logic levels and clipped sine wave outputs is required. Evaluate alternative TCXO models from the NDK NZ series or similar families that offer CMOS or LVDS outputs and broader voltage ranges. Ensure the replacement part matches the physical footprint and electrical specifications of the original design.

Part Context

This oscillator belongs to NDK's specialized TCXO lineup, distinct from standard crystals like the STDCSW2 series. It addresses applications demanding higher frequency stability than basic quartz crystals provide, without the complexity of discrete compensation networks. The 4-SMD package aligns with industry trends for miniaturized surface-mount technology.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation due to obsolescence. Review NDK's current TCXO portfolios, such as the NZ2520SHA series, for functional equivalents. Verify pinout compatibility and output waveform differences when selecting cross-references.
