QTO107-20.000MBL-T

Overview

The QTO107-20.000MBL-T is a quartz OCXO oscillator manufactured by QST, operating at a frequency of 20 MHz. It utilizes an SC cut crystal resonator with a load capacitance of 15 pF. The device features CMOS output format and operates on a 3.3V supply voltage. It supports a wide operating temperature range from -40°C to +85°C. The component is housed in a 6-SMD, No Lead package with dimensions of 9.7x7.5 mm.

Feature Summary

• Integrated oven-controlled stability for high-frequency precision
• CMOS logic output interface for digital circuit compatibility
• SC cut crystal resonator construction for enhanced thermal performance

Applications

• Telecommunications base station synchronization
• High-performance test and measurement equipment
• Precision timing systems requiring low phase noise

Procurement Notes

Verify the specific suffix 'BL' against official QST documentation to confirm pinout configuration and electrical tolerances. Ensure the 6-SMD no-lead package footprint matches the target PCB design. Confirm that the 3.3V supply requirement aligns with the system power architecture before finalizing procurement orders.

Selection Notes

Select this component when precise frequency stability is required across extreme temperature variations. The CMOS output simplifies integration with standard digital logic families. Consider the physical dimensions and surface-mount requirements for space-constrained designs. Validate thermal management strategies given the internal oven operation within the specified -40°C to +85°C range.

Part Context

This part belongs to the QTO107 series of quartz OCXOs. It shares the same form factor and core technology as variants like QTO107-30.720MBL-T and QTO107-20.000MBV-T. The series is designed for applications demanding superior frequency accuracy compared to standard TCXOs or VCXOs.

Replacement Considerations

Direct substitutes include other 20 MHz OCXOs in 6-SMD packages with CMOS outputs. Verify equivalent stability specifications and supply voltage requirements. Cross-reference mechanical dimensions to ensure board compatibility.
