QTT252-38.400MBN-T

Overview

The QTT252-38.400MBN-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST Products, LLC. It operates at a nominal frequency of 38.4 MHz with a frequency stability of ±2 ppm across an operating temperature range of -30°C to +85°C. The device utilizes a quartz resonator and delivers a clipped sine wave output format. It requires a supply voltage of 3.3V and is housed in a compact SMD2520-4P surface-mount package.

Feature Summary

Provides high-frequency stability of ±2 ppm over the industrial temperature range
Delivers a clipped sine wave output signal suitable for digital interfaces
Integrates temperature compensation circuitry within a small surface-mount footprint

Applications

Telecommunications equipment requiring precise clock synchronization
Wireless communication modules needing stable carrier frequencies
Industrial control systems operating in variable thermal environments

Procurement Notes

Verify the specific manufacturer designation, as documentation references both TXC Corporation and QST Products for this part number. Confirm the exact output waveform specification and supply voltage requirements against the latest official datasheet before integration. Ensure the SMD2520-4P package dimensions match the target PCB layout constraints.

Selection Notes

Select this component when a stable 38.4 MHz reference is required in space-constrained designs. The clipped sine wave output is appropriate for logic families compatible with such signals. Consider the ±2 ppm stability requirement relative to system jitter tolerance. Verify compatibility with the 3.3V power domain and ensure thermal management supports the -30°C to +85°C operational range.

Part Context

This oscillator belongs to the QTT252 series, characterized by its 2.5x2.0 mm package size. The series includes variants with different frequencies and stability grades. The QTT252-38.400MBN-T specifically addresses applications demanding precision timing in compact form factors, distinguishing it from larger through-hole or standard crystal oscillators.
