NSC5319B-26M

Overview

The NSC5319B-26M is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by NDK. It operates at a nominal frequency of 26 MHz and utilizes a clipped sine wave output signal. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. Frequency stability is specified at ±500 ppb. The component is housed in a compact 6-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm.

Feature Summary

• Integrates temperature compensation to maintain high frequency stability across operating conditions.
• Supports low-voltage operation with a 1.8V supply requirement.
• Features a compact surface-mount package suitable for space-constrained designs.

Applications

• Mobile communication devices
• Wireless data transmission modules
• Portable electronic equipment

Procurement Notes

Verify the specific orderable part number suffix, such as TR for tape and reel packaging, against the official datasheet to ensure correct handling and mounting specifications. Confirm that the 1.8V supply voltage aligns with the target circuit design requirements before procurement.

Selection Notes

Select this component when a stable 26 MHz reference is required in ultra-compact form factors. The ±500 ppb stability rating suits applications demanding precise timing without the complexity of discrete compensation circuits. Ensure the clipped sine wave output is compatible with the input impedance of the downstream logic or RF stage.

Part Context

This oscillator belongs to the NT2520SB series family from NDK, characterized by its small 2.5 mm x 2.0 mm footprint. The series is engineered for modern portable electronics where size and power consumption are critical constraints. It represents NDK's capability to provide high-reliability quartz-based solutions in miniaturized packages.

Replacement Considerations

Direct substitutes within the same series include other frequency variants of the NT2520SB line, such as the NSC5359B series, provided the frequency and pinout compatibility are verified. Cross-brand replacements require matching the 1.8V supply, 26 MHz frequency, and ±500 ppb stability specification.
