QTM252J-100.000MDJ-T

Overview

The QTM252J-100.000MDJ-T is a standard CMOS crystal oscillator manufactured by QST. It operates at a frequency of 100 MHz with a supply voltage of 1.8V. The device features a frequency stability of ±50ppm and supports an operating temperature range from -40°C to 105°C. It utilizes a 4-SMD, no-lead package with dimensions of 2.5x2.0 mm. The maximum supply current is 22mA, and it includes enable/disable functionality.

Feature Summary

• CMOS output signal generation
• Enable and disable control function
• Surface-mount 4-SMD no-lead packaging

Applications

• Digital signal processing systems
• Communication equipment clocking
• Microcontroller timing sources

Procurement Notes

Verify the manufacturer designation as QST or TXC Corporation through official datasheets. Confirm the specific suffix MDJ-T matches the required 1.8V supply and ±50ppm stability specifications. Ensure the 4-SMD no-lead package footprint aligns with PCB design requirements before procurement.

Selection Notes

Select this component for applications requiring a 100 MHz CMOS clock source with low voltage operation. Consider the -40°C to 105°C industrial temperature range for environmental suitability. Evaluate the 22mA current consumption against power budget constraints. Verify compatibility with system logic levels and enable pin requirements.

Part Context

This oscillator belongs to the QTM252 series, characterized by compact 2.5x2.0 mm surface-mount packages. The series offers various frequencies and voltage options, including 3.3V variants. The J suffix typically denotes specific tolerance or temperature grades within the product line.

Replacement Considerations

Cross-reference with QTM252-106.250MBE-T for similar form factor but different frequency and voltage. Check QTM252J-27.000MDJ-T for identical package and electrical characteristics except frequency. Verify pinout and enable functionality compatibility with existing designs.
