QTT216-38.400MBG-T

Overview

The QTT216-38.400MBG-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST, operating at a nominal frequency of 38.4 MHz. It utilizes quartz technology with a clipped sine wave output signal and requires a 3.3V DC supply voltage. The component features a compact surface-mount package measuring 2.0mm x 1.6mm x 0.8mm. It maintains a frequency stability of ±0.5 ppm across an extended industrial temperature range of -30°C to +85°C.

Feature Summary

• Temperature compensation ensures stable frequency performance across varying thermal conditions
• Compact surface-mount design suitable for space-constrained electronic assemblies
• Clipped sine wave output provides defined signal characteristics for digital interfaces

Applications

• Telecommunications equipment requiring precise clock synchronization
• Portable consumer electronics utilizing limited board space
• Industrial control systems operating in variable temperature environments

Procurement Notes

Verify the specific manufacturer designation, as some distributors list this model under TXC Corporation due to manufacturing relationships. Confirm the output waveform specification matches system requirements, as clipped sine wave outputs differ from standard square waves. Ensure the 3.3V supply voltage aligns with the target circuit design before procurement.

Selection Notes

Select this component when a small form factor TCXO is required for 38.4 MHz applications. The ±0.5 ppm stability rating supports high-precision timing needs within the specified temperature range. Consider the clipped sine wave output compatibility with downstream logic circuits during integration planning.

Part Context

This oscillator belongs to the QTT series of surface-mount TCXOs designed for compact electronic devices. The 2.0x1.6mm footprint represents a common size class for modern miniaturized communication modules. The 38.4 MHz frequency is frequently utilized in data transmission and interface synchronization contexts.

Replacement Considerations

The model 7Z-38.400MBG-T from TXC Corporation appears to share identical electrical specifications and physical dimensions. Verify pinout compatibility and exact waveform tolerances before substituting components in existing designs.
