QTM252J-30.000MDJ-T

Overview

The QTM252J-30.000MDJ-T is a standard clock oscillator manufactured by TXC Corporation, distributed under the QST brand. It operates at a frequency of 30 MHz with CMOS output and a supply voltage of 1.8V. The device features a frequency stability of ±50ppm and an operating temperature range of -40°C to 105°C. It utilizes a 4-pin CSMD package with dimensions of 2.5x2.0 mm. Maximum supply current is 22mA, and it supports enable/disable functionality.

Feature Summary

• Low jitter and phase noise performance
• CMOS output signal compatibility
• Enable/Disable control capability

Applications

• Standard clock generation for digital circuits
• Embedded systems requiring precise timing
• Consumer electronics with space constraints

Procurement Notes

Verify manufacturer designation as TXC Corporation despite QST branding. Confirm 4-pin CSMD package type and 2.5x2.0mm footprint. Ensure 1.8V supply voltage requirement matches system design. Check frequency stability specification of ±50ppm against application tolerance needs.

Selection Notes

Select this component when low profile size and low power consumption are critical. The 1.8V operation suits modern low-voltage logic families. Verify thermal requirements fall within the -40°C to 105°C industrial range. Consider the CMOS output interface compatibility with target microcontrollers or processors.

Part Context

This part belongs to the QTM252J series of ceramic quartz oscillators. It shares the 2.5x2.0mm form factor with other variants in the family. The series offers various frequencies and voltage options while maintaining consistent physical dimensions and pinout configurations for board layout flexibility.

Replacement Considerations

QTM252J-26.000MDJ-T and QTM252J-27.000MDJ-T are confirmed substitutes within the same series offering different frequencies.
