QTT325-16.368MBN-T

Overview

The QTT325-16.368MBN-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST Products, LLC. It operates at a nominal frequency of 16.368 MHz with a high frequency stability of ±2 ppm across the industrial temperature range of -30°C to +85°C. The device utilizes a clipped sine wave output format and requires a 3.3V supply voltage. It is housed in a compact 4-SMD, no-lead package measuring 3.2mm x 2.5mm, designed for surface-mount assembly.

Feature Summary

• Temperature compensation ensures stable frequency performance across wide industrial temperature ranges
• Compact surface-mount package design suitable for space-constrained electronic applications
• Clipped sine wave output format compatible with standard digital logic interfaces

Applications

• Wireless communication modules requiring precise clock synchronization
• Portable electronic devices needing low-power stable timing sources
• Industrial control systems operating in variable thermal environments

Procurement Notes

Verify the specific manufacturer part number against official QST documentation to ensure authenticity. Confirm that the required frequency stability of ±2 ppm and the -30°C to +85°C operating range meet your system's environmental specifications. Ensure compatibility with 3.3V logic levels and clipped sine wave input requirements of the receiving circuitry before procurement.

Selection Notes

Select this component when a stable 16.368 MHz reference is needed in a small form factor. Consider the ±2 ppm stability requirement against your system's jitter tolerance. Verify that the clipped sine wave output does not require additional buffering or level shifting for your specific microcontroller or RF front-end interface.

Part Context

This TCXO belongs to the QTT series of temperature-compensated oscillators from QST. These components are designed to replace standard crystals or OCXOs where size and power consumption are critical constraints. The series offers various frequencies and stability grades, with this specific model targeting applications demanding moderate stability in a compact SMD footprint.

Replacement Considerations

Direct substitutes must match the 16.368 MHz frequency, ±2 ppm stability, 3.3V supply, and 4-SMD no-lead package dimensions. Verify pinout compatibility and output waveform characteristics. Cross-reference with other manufacturers' TCXO series offering similar thermal compensation and form factors if QST availability is limited.
