QTT252-50.000MBG-T

Overview

The QTT252-50.000MBG-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST Corporation Limited. It operates at a nominal frequency of 50 MHz with a high stability of ±500 ppb. The device utilizes a clipped sine wave output and requires a supply voltage of 3.3V. It functions within an operating temperature range of -30°C to +85°C. External decoupling capacitors are required for the circuit, and control voltage compatibility exists for 3.3V or 2.5V supply configurations.

Feature Summary

• Temperature-compensated design ensures stable frequency performance across varying thermal conditions
• High frequency stability achieved through precision quartz resonator technology
• Clipped sine wave output suitable for sensitive RF and clocking applications

Applications

• Precision timing circuits requiring low phase noise
• Telecommunications equipment clock sources
• Test and measurement instrumentation
• Industrial control systems operating in variable temperatures

Procurement Notes

Verify the specific suffix codes against official QST documentation to confirm exact electrical characteristics and packaging details. Ensure that external decoupling capacitors are included in the design schematic as mandated by the component specifications. Confirm supply voltage requirements align with the 3.3V standard before integration into the target system architecture.

Selection Notes

Select this component when high frequency stability is critical for system synchronization. The clipped sine wave output necessitates compatible input stages in downstream logic. Verify that the operating temperature range meets the environmental constraints of the intended deployment scenario. Ensure power supply rails are stable to maintain the specified ±500 ppb accuracy.

Part Context

This model belongs to the QTT252 series of TCXOs from QST Corporation Limited. The series focuses on providing reliable clock signals for applications demanding precise timing. The specific part number indicates a 50 MHz frequency variant designed for robust performance in commercial and industrial environments.

Replacement Considerations

Consult official QST substitution guides for direct equivalents. Cross-reference pinouts and electrical parameters carefully when considering alternative manufacturers. Verify that any substitute maintains the same clipped sine wave output type and supply voltage requirements.
