QTM252J-50.000MDJ-T

Overview

The QTM252J-50.000MDJ-T is a standard clock oscillator manufactured by TXC Corporation under the QST brand. It operates at a frequency of 50 MHz with a CMOS output type. The device supports a supply voltage of 1.8V and offers a frequency stability of ±50ppm across an operating temperature range of -40°C to +105°C. It features low jitter and phase noise characteristics, housed in a compact 2.5mm x 2.0mm surface-mount package.

Feature Summary

• CMOS output interface for digital logic compatibility
• Low jitter and phase noise performance
• Wide industrial temperature range operation
• Compact surface-mount footprint

Applications

• Standard clock signal generation
• Digital system timing references
• Embedded controller clock sources

Procurement Notes

Verify the specific ordering suffix 'D' confirms the 1.8V supply voltage requirement. Ensure the 'J' suffix matches the required ±50ppm stability and -40°C to +105°C temperature range. Confirm the package dimensions align with PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a 50 MHz CMOS clock source is required with strict size limitations. The 1.8V supply voltage makes it suitable for low-power portable or battery-operated devices. Consider the ±50ppm stability if precise timing synchronization is not critical compared to higher-grade oscillators.

Part Context

This part belongs to the QTM252J series of quartz ceramic oscillators. The series includes various frequencies and voltage options, such as 3.3V variants like the QTM252J-11.2896MBJ-T. The J suffix specifically denotes the extended temperature range and stability specifications within this product family.

Replacement Considerations

Direct substitutes include other 50MHz 1.8V CMOS oscillators from different manufacturers. Cross-reference pinouts and electrical parameters carefully. Verify that alternative components meet the same -40°C to +105°C operating temperature range and ±50ppm stability requirements.
